Don't build host-xz needlessly

Since commit d1f325f554cab (xzcat: treat as host prerequisite and build if
needed) host-xz is always built when the host does not have xz installed.
Removed all other host-xz dependencies.

[Peter: don't drop for host-squashfs, as that needs libxz development files]

snmppp: update download URL

The filename of the SNMP++ sources has changed.
The old one is still working because the server automatically redirects to the
new file, but it is safer to use the official name.

snmppp: add option to enable logging

SNMP++ logging can be overly verbose, and according to the SNMP++
documentation, disabling logging "increases performance drastically and
minimizes memory consumption".

snmppp: add option to disable SNMPv3 support

Disabling SNMPv3 support also removes the dependency on OpenSSL, which is
pretty large (over 2 MB of uncompressed filesystem size on an ARM926 platform).

BR2_PACKAGE_SNMPPP_SNMPV3 defaults to yes for backward compatibility with
previous Buildroot releases, where SNMPv3 was always enabled.
