dev-db/mariadb: unconditionally pass -fno-tree-vectorize

Followup to d72826a5df. Jens reports
in the bug that he sees a crash w/ GCC 15 in my_convert too. It's very
likely the same problem: 15 at least already had some peeling for alignment
changes and we know the code in MariaDB is broken here.

Don't bother conditionalising it on GCC as Clang accepts -fno-tree-vectorize
too and it could show up there too of course as it's UB.

And revbump here as well given it clearly affects real users, not just
those w/ experimental (16) GCC.
