fs/qnx6: Fix building with GCC 15

qnx6_checkroot() had been using weirdly spelled initializer - it needed
to initialize 3-element arrays of char and it used NUL-padded
3-character string literals (i.e. 4-element initializers, with
completely pointless zeroes at the end).

That had been spotted by gcc-15[*]; prior to that gcc quietly dropped
the 4th element of initializers.

However, none of that had been needed in the first place - all this
array is used for is checking that the first directory entry in root
directory is "." and the second - "..".  The check had been expressed as
a loop, using that match_root[] array.  Since there is no chance that we
ever want to extend that list of entries, the entire thing is much too
fancy for its own good; what we need is just a couple of explicit
memcmp() and that's it.
