selftests/damon/sysfs.sh: test all files in quota goal dir

Browse Source 
DAMON sysfs interface for DAMOS quota has quite extended since its initial
introduction.  The test case for that in DAMON sysfs interface essential
file operations test (sysfs.sh) has not accordingly extended, though. 
Extend the test case to test all existing files.
