The mechanism currently used to pass data from the dEQP child process
executed in a crosvm guest environment towards the deqp-runner wrapper
script that starts the crosvm instance is based on creating, writing
and reading regular files.
In addition to the main drawback of using the storage, this approach
is potentially unreliable because the data cannot be transferred in
real-time and there is no control on ending the transmission. It also
requires a forced sleep for syncing the content, while the minimum
amount of time necessary to wait cannot be easily and safely
determined.
Replace this with an IPC based on the virtio transport for virtual
sockets (virtio-vsock).

crosvm-runner.sh was using `export -p` to create an environment script
for the virtualized system, but this command will dump every declared
environment variable in the system, which includes Gitlab's CI variables
with sensitive data, such as passwords and auth tokens.
Replacing `export -p` to `generate-env.sh`, which only exports the
necessary variables for Mesa CI jobs.
Extra changes:
* Stop changing ${PWD} variable programmatically in scripts. ${PWD} is a
variable used by most prolific coreutils and bash commands, such as `cd`
and `pwd`, besides it is set by subshells [1]; changing this variable
may lead to complex situations.
As drop-in replacement for ${PWD}, use ${DEQP_BIN_DIR} to flag that
there is a special folder where dEQP should be run.
* Double quote path and array variables. See: https://github.com/koalaman/shellcheck/wiki/SC2086
* Do not export variables directly from commands output. See: https://github.com/koalaman/shellcheck/wiki/SC2155

```
$ cd /tmp
$ export PWD=test; bash -c 'echo $PWD'
/tmp
```
v2:
- Revert $DEQP_BIN_DIR quoting in crosvm-runner.sh and crosvm-init.sh
- Log all the passed variables to stdout, to help with debugging when
new variable are needed to be put in `generate-env.sh`
v3:
- Revert $DEQP_BIN_DIR quoting leftovers

Currently we run deqp-runner inside a single VM, which makes very poor
use of the available CPUs because Virgl has a bottleneck in the VMM that
serializes everything.
With this change, we can run several Crosvm instances in a runner and
make full use of the CPUs. Getting the same coverage with 3 runners
instead of 6.

Sometimes, the VM powered off before all the output from the guest got
to the console.
