[PATCH testsuite 2/3] tests/filesystem: pipe "yes" to mkfs.* to fix jfs test

[Ondrej Mosnacek <omosnace@xxxxxxxxxx>]

mkfs.jfs is reluctant to overwrite the device without the user's
consent, so shout a stream of y's on it to avoid the test getting stuck.
We can't universally pass -q to mkfs.*, because not all mkfs.* tools
support it.
