022: ignore fsstress file count

022: ignore fsstress file count

The recently added fsstress operations result in a different
number of directories and files being created for xfsdump test
022, which causes the test to fail since the expected xfsrestore
output records these numbers. Filter out the numbers to prevent
this from breaking in the future.

Also increase the number of fsstress operations used to populate
the filesystem so that we get roughly the same number of
directories and files as we used to for this test.
