UnixProcess: Improve error message for generic/unknown error codes.
Replace strcmp with strstr to return a more understandable
error message. Using strcmp is wrong, because if errnum is
not known, strerror will return 'Unknown error XXX' including errnum,
so strict comparison against 'Unknown error' does not work.
Searching for a substring with strstr fixes this issue.
It is hard to trigger incorrect behavior from java code
because it only happens for error codes that are not already
handled in errno.h; bug 117755069 tracks the follow-up work of
handling remaining error code.
Bug: 110019823
Test: cts-tradefed run cts -m CtsLibcoreTestCases --abi arm64-v8a
Test: Manually set errnum variable to value 135, which is not
defined anywhere in errno.h to confirm the error message
equals to expected.
