dev-db/mariadb: workaround unaligned access

Browse Source 
Pass -fno-tree-vectorize with GCC 16 for now. I've reported it upstream
to MariaDB and they've acknowledged the problem. Note that the "same"
code is in MySQL but that was fixed quite some years back.

Bug: https://jira.mariadb.org/browse/MDEV-37148
Closes: https://bugs.gentoo.org/959423
