[gdb/testsuite] Fix false negative in have_host_locale
In test-case gdb.tui/pr30056.exp we check for:
...
require {have_host_locale C.UTF-8}
...
The "C.UTF-8" is normalized by have_host_locale to "c.utf8", before trying to
find it in the list returned by host_locales.
On my development platform, "locale -a" lists C.utf8, which is normalized to
"c.utf8" by host_locales, so there's a match and have_host_locale returns true.
On another platform however, "locale -a" lists C.UTF-8, which is normalized to
"c.utf-8" by host_locales, so there's no match and have_host_locale returns false.
Fix this by also dropping the dash in host_locales.
Tested on x86_64-linux.
