crash: Preserve cached os version files

/etc/os-release and /etc/lsb-release are cached in /var/spool/crash so
that kernel crashes can be correctly matched up to the running version
at the time of the crash (details in crbug.com/590757).

The logic that cleans up orphaned crash reports is picking up these
files and deleting them 24 hours after boot.  Fix this by explicitly
preserving the two cached files.

BUG=chromium:768467
TEST=Manually touched files in /var/spool/crash and verified that
     crash_sender doesn't delete them.
