These functions contain complex logic and parse user input. It shall be
valuable to fuzz these functions to prevent regression.

ReadFstabFromFp() have two callers right now, ReadFstabFromFile() and
ReadFstabFromDt(). ReadFstabFromFile() opens a FILE* and pass it to
ReadFstabFromFp(), and ReadFstabFromDt() wraps a std::string::c_str()
buffer in a FILE* adaptor with fmemopen().
There's no need for such adaptor, just change ReadFstabFromFp() to
accept std::string and we're good.

This is probably an overkill, but still, add a collection of
interesting keywords that may appear in a fstab file.
Also add myself to the "CC" list of this fuzz target.
BYPASS_INCLUSIVE_LANGUAGE_REASON="slave" or MS_SLAVE is a mount flag

Just a modest initial implementation. Uses the fuzz data as the fstab
file content directly.
