classes/image: Use xargs to set file timestamps
Instead of having find directly invoke touch for each file in the root
file system, pass a list to xargs for batching. This significantly
reduces the number of times the touch program is invoked and speeds up
the do_image task time:
PKG TASK ABSDIFF RELDIFF CPUTIME1 -> CPUTIME2
my-image do_image -45.3s -94.2% 48.1s -> 2.8s
Cumulative cputime:
-44.3s -92.3% 00:48.1 (48.1s) -> 00:03.7 (3.7s)
