Subject: [PATCH 45/53] tests: t3310-flags.sh: Query libparted for all flags to
 be tested

Replace scanning the documentation for an incomplete list of flags with
querying libparted for the complete list of supported flags via the
added helper print-flags.

Correct $ME -> $ME_ in the warning messages.  Improve the warning
messages by including the table type and flag name not correctly set or
cleared.

Plus minor changes:
(1) use slightly longer variable name primary_or_name;
(2) use longer test partition name PTNNAME; and
(3) stop shortening parted unit command to u.
