[RFC PATCH 07/11] selftests/damon/sysfs.sh: test all files in quota goal dir

[SeongJae Park]

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.
