package/heirloom-mailx: fix comment about ignore CVE-2014-7844

In commit
15972770cf34ed0b0ba330e3cc42c04f1c80c3c8 ("package/heirloom-mailx:
security bump to version 12.5-5 from Debian"), we added CVE-2014-7844
in HEIRLOOM_MAILX_IGNORE_CVES, but with the wrong comment about it: it
is a different patch in the Debian stack of patches that fixes
it. Indeed the description of patch
0011-outof-Introduce-expandaddr-flag.patch is:

=====================================================================
Subject: [PATCH 1/4] outof: Introduce expandaddr flag

Document that address expansion is disabled unless the expandaddr
binary option is set.

This has been assigned CVE-2014-7844 for BSD mailx, but it is not
a vulnerability in Heirloom mailx because this feature was documented.
=====================================================================
