generic: Check the stx_attributes settable by chattr
Check the stx_attributes that can be set by calling chattr.
The script probes the filesystem with chattr to find out which of
+a, +c, +d and +i are supported before testing combinations of
attrs. Note that if a filesystem supports chattr with these, but
doesn't paste the flag values into stx_attributes, the test will
fail as there's no way to distinguish cleared from unset.
Certain chattr flags are reflected in specific stx_attributes flags:
chattr flag stx_attributes flag
+a STATX_ATTR_APPEND
+c STATX_ATTR_COMPRESSED
+d STATX_ATTR_NODUMP
+i STATX_ATTR_IMMUTABLE
