devtool deploy-target tars up the build output and pipes it through
ssh to the target, where it's extracted with "tar xv". If the
target's clock is behind the host, tar prints a "time stamp ... is
... in the future" warning per file, since the archived mtimes come
from the host.

Add -m (--touch) so tar sets mtimes to the current time on extraction
instead of restoring them from the archive, avoiding the warning.
Supported identically by GNU tar and BusyBox tar.
