[gdb/testsuite] Make gdb.arch/amd64-gs_base.exp unsupported for i386
With target board unix/-m32 I run into:
...
(gdb) print /x $fs_base^M
$1 = void^M
(gdb) FAIL: gdb.arch/amd64-gs_base.exp: print fs_base
...
The problem is that the fs_base register is not supported for i386.
Fix this by making the test unsupported if fs_base/gs_base don't show up in
info register sys output.
Tested on x86_64-linux.
