mail: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

The following distfiles were unfetchable (possibly fetched
conditionally?):

./mail/qmail/distinfo netqmail-1.05-TAI-leapsecs.patch

Log message:
mail: Remove SHA1 hashes for distfiles

Log message:
Remove DJB_RESTRICTED, no longer used.

Log message:
Retire 'djbware-errno-hack' and associated options.mk cleverness.
Instead:

1. Package makefiles including their own options.mk
2. Packages say "SUBST_CLASSES+=djberrno" to get the hack, if needed
3. Packages adjust SUBST_FILES.djberrno, if needed

Should fix bulk build failures due to multiple inclusions of options.mk
and/or incorrect definitions of DJB_ERRNO_HACK.

Approved during the freeze by wiz@.

all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
all: replace SUBST_SED with the simpler SUBST_VARS

pkglint -Wall -r --only "substitution command" -F

With manual review and indentation fixes since pkglint doesn't get that
part correct in every case.

Log message:
Support user-destdir.
