egl: cut down static storage size for {Version,ClientAPI}String

Both seems to be excessively long, namely:

ClientAPIString can get up-to 47 based on current code, while the name
of the driver can dictate the length of the VersionString, currently it
is around 11. Let's pad each to 100, rather than the current 1000.
