base-files: sysupgrade stage2: fix losetup detection

Browse Source 
If the busybox applet losetup was selected, `command -v` selects that
during sysupgrade. As this applet is in another path and doesn't cover
the '-D' option which is used to make sure user-defined loop devices
are no longer active during sysupgrade.
Detect losetup at the path of the full utility to avoid error messages
in case of the busybox applet being selected.
