criu-print: use %# to print hex values w/ width specified

If we print "0x" with width specifier, it may go away which is not nice:
(00.005258) 21858 fdinfo 0: pos: 0x               0 flags:           100002/0
(00.004589)     Collected: ino 0x    51fd family    2 type    1 port    64000 state 10 src_addr 0.0.0.0

This patch is generated with the following sed one-liner:
find ./* -type f -print0 | xargs -0 sed -i '/pr.*/s/0x%\([0-9]\+\)/%#\1/g'

Don't know if we should change all 0x%*anything* printing to %#*anything*,
but where we use field width I think we should.

Impact: Just bothered by eyes, cleanup.
