Found (and fixed) ausearch checkpoint bug

When running ausearch against a single file with the --checkpoint option, the file's
device number and inode are not recorded in the resultant checkpoint file.

That is for the most recent released audit package
   [root at auditdtest audit-userspace]# rpm -q audit
   audit-3.0-0.5.20181218gitbdb72c0.fc29.x86_64

We see the error via
   [root at auditdtest audit-userspace]# rm -f /tmp/checkpoint.txt; ausearch --input
   /var/log/audit/audit.log.2 --checkpoint /tmp/checkpoint.txt > /dev/null; cat
   /tmp/checkpoint.txt
   dev=0x0
   inode=0
   output=auditdtest.auditd.test.dom 1545477871.508:116403 0x514

Which is incorrect. The following is correct.
   [root at auditdtest audit-userspace]# rm -f
   /tmp/checkpoint.txt;  ./src/.libs/ausearch --input /var/log/audit/audit.log.2 --
   checkpoint /tmp/checkpoint.txt > /dev/null; cat /tmp/checkpoint.txt
   dev=0xFD00
   inode=25326469
   output=auditdtest.auditd.test.dom 1545477871.508:116403 0x514
   [root at auditdtest audit-userspace]# 

A Pull Request with the fix has been submitted on github -
