Subject: [PATCH] core/mount: skip incomplete mountinfo entries

Skip /proc/mountinfo entries for which libmount returns a NULL pointer
for 'source' or 'target'. This happened on Semaphore CI's build servers
when the test suite is run.

(cherry picked from commit c0a7f8d3cb757cf750fc6788df0d215f6457c09d)
