libkrad allows to establish connections only to UNIX socket in FIPS
mode, because MD5 digest is not considered safe enough to be used for
network communication. However, FreeRadius requires connection on TCP or
UDP ports.
This commit allows TCP or UDP connections in FIPS mode if destination is
localhost.

change_set_password() was changed to prefer TCP. However, because
UDP_LAST falls back to UDP after one second, we can still get a replay
error due to a dropped packet, before the TCP layer has a chance to
retry.
Instead, try k5_sendto() with NO_UDP, and only fall back to UDP after
TCP fails completely without reaching a server. In sendto_kdc.c,
implement an ONLY_UDP transport strategy to allow the UDP fallback.

In kr_attrset_decode(), explicitly treat the length byte as unsigned.
Otherwise attributes longer than 125 characters will be rejected with
EBADMSG.
Add a 253-character-long NAS-Identifier attribute to the tests to make
sure that attributes with the maximal number of characters are working
as expected.

CMS digest and signature algorithm for the anonymous PKINIT is changed
from SHA-1 to SHA-256. SHA-1 hasn't been considered secure anymore for
this kind of purposes for some years already.

1.15.1 was ~2017, so there is no need to support upgrades from such old
systemd. This allows the dependency on grep to be dropped. grep pulls
in pcre, but most other programs in the core group depend on the newer
pcre2, so it's nicer to avoid pulling in pcre in minimal installations.
