testsuite: Also exclude `*-*-kfreebsd*-gnu' from STB_GNU_UNIQUE tests

Fix commit 02e0be69012a ("mbind gas tests and supports_gnu_osabi
testsuite infrastructure") and also match `*-*-kfreebsd*-gnu' targets
when determining whether STB_GNU_UNIQUE binding is supported for
symbols.  These targets use the same BFD vectors as `*-*-freebsd*' do,
choosing ELFOSABI_FREEBSD, and therefore need to be treated analogously.

This fixes numerous regressions, e.g.:

mips-kfreebsd-gnu  -FAIL: weaken STB_GNU_UNIQUE symbols
mips-kfreebsd-gnu  -FAIL: strip on STB_GNU_UNIQUE
mips-kfreebsd-gnu  -FAIL: diagnostics for visibility directives
mips-kfreebsd-gnu  -FAIL: ld-unique/pr21529
mips-kfreebsd-gnu  -FAIL: Linker setting GNU OSABI on STB_GNU_UNIQUE symbol (PR 10549)

caused by the missing feature:

.../gas/testsuite/gas/elf/visibility.s:14: Error: symbol type "gnu_unique_object" is supported only by GNU targets
