[test] Update to new sample skip API

Signed-off-by: Claudio Matsuoka <cmatsuoka@gmail.com>
Update sample skip API to use xmp_set_player

Use xmp_set_player() with parameter XMP_PLAYER_SMPCTL to enable or
disable sample loading when loading a module instead of defining
a different call.

Add player flag to return module-specific flags

Module-specific flags are player flags applied if a module matches
an entry in a quirk table. Being able to set this separately from
player-wide flags allows us to disable quirk table entries if needed
(such as in modules.conf in xmp-cli).
