testsuite: Allow setting gpp_std_list in configuration files
This allows the gpp_std_list variable to be set in ~/.dejagnurc instead
of using the GXX_TESTSUITE_STDS environment variable. This is
consistent with how other defaults such as tool_timeout can be set.
The environment variable can still be used to override the default.
gcc/testsuite/ChangeLog:
* lib/g++-dg.exp: Update comments.
* lib/g++.exp (gpp_std_list): Check for an existing value before
setting it to an empty list.
