-----------
tools/syz-imagegen: accept filesystem descriptions as input

Don't generate just the hard-coded list of filesystems, but also
generate seeds for the externally supplied json description of a
filesystem.

Add a special syscall attribute to help syz-imagegen guess the actual
filesystem name from the syz_mount_image variant name.

Log Message:
-----------
tools/syz-imagegen: rewrite combination generation

Introduce a new Filesystem parameter - the maximum number of resulting
seeds.

If the total number of flag combinations exceeds this number, switch to
generating a covering array (that is, make sure that all flag value
pairs are covered, or at least as many of them as possible).
