selftests/damon/sysfs.sh: test multiple probe dirs creation

Browse Source 
DAMON sysfs essential file operations test (sysfs.sh) was extended to test
DAMON probes sysfs directory, by commit 14885da09b
("selftests/damon/sysfs.sh: test probes dir").  Unlike other DAMON sysfs
files, it is testing only a single directory case.  Extend it for multiple
directories.
