package-installs: add list to arch and "not-arch" list

Icf8a075224833fcfbbe2128e8802ff41c39f3c09 looked rather ugly, and it's
easy for us to expand the processing done in the arch list.

Change "arch" to a comma-separated list of architectures that should
match for install.

Add a "not-arch" list which will exclude the package from installation
on those architectures.  (An aside -- I considered making it just he
one list with foo,!bar,moo but ! has special meaning in YAML, so it's
easier to have two lists).

$ ARCH=ppc64 package-installs-squash --elements ironic-agent --path=./elements/ /dev/stdout | grep dmidecode
$ ARCH=ppc64 package-installs-squash --elements ironic-agent --path=./elements/ /dev/stdout | grep lshw
    "lshw",
$ ARCH=amd64 package-installs-squash --elements ironic-agent --path=./elements/ /dev/stdout | grep lshw
$ ARCH=amd64 package-installs-squash --elements ironic-agent --path=./elements/ /dev/stdout | grep dmidecode
    "dmidecode",

Setting the arch property causes the package only to be installed for the

for more information.
The ``arch`` property is a comma-separated list of architectures to
install for. The ``not-arch`` is a comma-separated list of
architectures the package should be excluded from. Either ``arch`` or
``not-arch`` can be given for one package - not both. See
documentation about the ARCH variable for more information.

features:
- The ``package-installs`` element now supports a list of
architectures to install the package for in the ``arch`` field and
negative matching with a ``not-arch`` field. This allows greater
flexibility when installing packages for only some architectures.
