package/mutt: security bump to version 2.0.7

Fix CVE-2021-32055: Mutt 1.11.0 through 2.0.x before 2.0.7 (and NeoMutt
2019-10-25 through 2021-05-04) has a $imap_qresync issue in which
imap/util.c has an out-of-bounds read in situations where an IMAP
sequence set ends with a comma. NOTE: the $imap_qresync setting for
QRESYNC is not enabled by default.
