common: add helper function _flakey_drop_and_remount
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.
