nut: New package for Network UPS Tools

An older version of nut is in oldpackages. This commit is based on that
package and bumps the version to the latest release along with unifying
the server and client packages. More build options are provided for any
custom configuration but the defaults provide a working client and
server install which only needs a UPS driver. Drivers still build as
individual packages to minimise bloat. SSL support has also been added.

perl: Make I8/I16/I32 types explicitly signed for PPC

Type signedness is undefined for char. char may actually be unsigned for
some CPUs.
This fixes various bugs on PPC, like negative array indices.

perl: Don't try to link against libnsl

And also remove all other references to avoid confusion.
libnsl isn't really needed. Removing it allows glibc based
toolchains to build perl.
