common: add helper function _flakey_drop_and_remount

Browse Source 
To avoid having many tests repeating the following pattern:

        _load_flakey_table $FLAKEY_DROP_WRITES
        _unmount_flakey

        _load_flakey_table $FLAKEY_ALLOW_WRITES
        _mount_flakey

add the helper function _flakey_drop_and_remount to remove
the existing duplicated code and serve as a shortcut.
