fortify: Ensure that __glibc_fortify condition is a constant [BZ #29141]
The fix c8ee1c85 introduced a -1 check for object size without also
checking that object size is a constant. Because of this, the tree
optimizer passes in gcc fail to fold away one of the branches in
__glibc_fortify and trips on a spurious Wstringop-overflow. The warning
itself is incorrect and the branch does go away eventually in DCE in the
rtl passes in gcc, but the constant check is a helpful hint to simplify
code early, so add it in.
Resolves: BZ #29141
