[PATCH] [compiler-rt] log-path_test testcase - make the invalid path more invalid

[Kuba Brecka]

The ASan test/asan/TestCases/log-path_test.cc testcase uses `/INVALID` as an invalid path and expects that the program will not be allowed to create or write to that file. This actually is a valid writable path on one of my setups. Let's make the path more invalid.
