Add error handling on realpath() call.

Browse Source 
(Without this, it happened for me that realpath() failed returning
undef for the default vardir. This in turn caused mysql-test-run.pl to
delete the source mysql-test/ directory.)

Backport from 10.1, it's not nice to get one's source directory nuked
by a rouge mysql-test-run.
