fstests: print symbolic names for fiemap flags

Commit Message

Josef Bacik Nov. 12, 2021, 8:37 p.m. UTC

My nightly btrfs tests are failing on my configs with -o compress because the
extents have FIEMAP_EXTENT_ENCODED set, which throws the golden output off.

Fix this by changing the filter helper to spit out symbolic names for SHARED and
LAST (these tests only care about SHARED).  Then change the golden output to
match the new output of the filter.  With this patch my -o compress configs now
pass these tests.
