mail/offlineimap: Add dependency on net/py-rfc6555

From J. Lewis Muir via wip.

OfflineIMAP requires the rfc6555 module, but the package is missing the
dependency declaration.  Without rfc6555, OfflineIMAP builds but does
not run; it fails with a stack trace that ends like this:

  File "[...]/offlineimap/imaplibutil.py", line 22, in <module>
      import rfc6555
      ImportError: No module named rfc6555

Log message:
*: recursive bump for Python 3.11 as new default

Log message:
*: Revbump packages that use Python at runtime without a PKGNAME prefix

Log message:
*: python2 egg files are back, add them to the PLISTs

Log message:
offlineimap: convert to egg.mk
