gcov-dump: Print PATHS tag

Print the record associated with the PATHS tag.  While it just prints
the number of prime paths for the function, this is more useful than
the UNKNOWN it would otherwise print.

Before:
...
demo.gcno:    01450000:  31:LINES
demo.gcno:                  block 6:`demo.c':13
demo.gcno:    01490000:   4:UNKNOWN

After:
...
demo.gcno:    01450000:  31:LINES
demo.gcno:                  block 6:`demo.c':13
demo.gcno:    01490000:   4:PATHS 5 paths
