[PATCH] utilities: kernelscan.sh: Check that the file exists

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

kernelscan.sh makes assumptions about which files to scan and
this can change over time because files get renamed or removed from
the kernel. So add a check so see if the source exists before trying
to scan it.
