testsuite: Fix gcc.dg/vect/vect-fmax-1.c etc. on SPARC [PR104756]

The gcc.dg/vect/vect-fmax-?.c etc. tests FAIL on 32 and 64-bit SPARC:

As discussed in the PR, they require vect_float support, but the tests
don't declare it.

This patch fixes this.

Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11.
