sysutils/e2fsprogs: update to new upstream release v1.46.0
The major item in porting is to switch from GNU libc's qsort_r()
interface to ours, but see https://reviews.freebsd.org/D17083
Also, it appears at cursory glance that it takes the FUSEFS option
to get HAVE_PTHREAD_H #defined. Just pass -DHAVE_PTHREAD_H through
CPPFLAGS without further investigation.
Finally, there appears to be some confusion around __u64 vs.
unsigned long long, we get format string complaints. Use <inttypes.h>
and leverage the PRIu64 macro.
I do not intend to MFH this.
