[clang] [PS4/PS5][Driver] Allow unified-lto.c test to find .*ld.exe (PR #101034)

It's common in SIE development environments to have the PlayStation linkers on the %PATH%. In such cases, the driver will resolve the linker name to an existing executable, replete with ".exe" extension. Update recent modifications to clang/test/Driver/unified-lto.c to allow for this.
