liblog: test: CTS: enoent does not qualify

Eliminate liblog@enoent CTS test as it is bypassed on "user" builds
in commit "liblog: test: enoent requires userdebug or eng to run".
This prevents time wasted running a test that bypasses during CTS.

Test: CtsLiblogTestCases_list --gtest_list_tests |
      (grep enoent && echo FAILED)
