[PATCH] image: let mksquashfs4 use all processors

[Stijn Tintel]

Drop the -processors argument from the mksquashfs4 call, so it will use
all available processors. This dramatically reduces the time to create
squashfs filesystems.

The times below are observed when building an image for my main router,
the WatchGuard Firebox M300 (qoriq target):

Before:
real    4m45,973s

After:
real    0m23,497s
