  [compiler-rt] Disable default config files for tests

Without this, if hardening measures like FORTIFY_SOURCE are are in
/etc/clang/*.cfg, many sanitizer tests will die before the sanitizer
can trap the problem being tested, because e.g. the _chk variants
of common functions will abort first.

This gets the number of failing tests down from 42->3 for me (and the
remaining 3 are unrelated).
