sysutils/e2fsprogs: misc/e2fsprogs-libblkid: fixes

• for libblkid, fix a buffer size when parsing device names to make room for a trailing '\0' character from sscanf(). (This was a long-standing bug in our local patch.)

• patch out qsort_r redeclarations from the sort_r library that are incompatible with FreeBSD since it aligned with GNU qsort_r() API

• remove FreeBSD 14-CURRENT BROKEN= tag.
