Some minor tweaks in tramp-tests.el

* test/lisp/net/tramp-tests.el (tramp-test05-expand-file-name-relative):
Let it pass for all gfvs based methods.
(tramp-test24-file-name-completion): Run method and host
completion for all syntaxes only when expensive tests are enabled.
Do not check host completion for gvfs based methods.
(tramp--test-gvfs-p): Add optional METHOD argument.
(tramp--test-afp-or-smb-p): Remove.
