Revert "Revert "write a log file about OpenGL driver""

This reverts commit 2ebca292.

The build breakage in gengal was caused by the global variable
aCacheFolder, which is initialized by a call to
rtl::Bootstrap::expandMacros(), which initializes the global
FundamentalIni object before tools::extendApplicationEnvironment() gets
a chance to set URE_BOOTSTRAP, so FundamentalIni is empty.
