setup: Fix image type detection on recent kernels.

When running outside chroot, the image type detection will use "strings" with
pattern grep -w "root=". However this won't work for recent kernels using
 root=PARTUID=%U/PARTNROFF=1.

Since "-w" is already checking "root" as a single word, we should remove '='
from the pattern.
