Following change will rename 'monitor_on' DAMON debugfs file to
'monitor_on_DEPRECATED', to make the deprecation unignorable in runtime. 
Since it could make DAMON selftests fail and disturb future bisects,
update DAMON selftests to support the change.

When running the test for the damon subsystem, there are a lot of
warnings because test scripts do not have executable permission,
for example:

Warning: file debugfs_attrs.sh is not executable
Warning: file debugfs_schemes.sh is not executable
Warning: file debugfs_target_ids.sh is not executable
...

This patch adds executable permission to test scripts to eliminate
these warnings.

Currently, the single test program, debugfs.sh, contains all test cases
for DAMON.  When one of the cases fails, finding which case is failed
from the test log is not so easy, and all remaining tests will be
skipped.  To improve the situation, this commit splits the single
program into small test programs having their own names.
