packaging: add Makefile

Allow building the spice installer and building/installing the ovirt
installer.

Allow passing DISPLAYED_VERSION to make.

Allow passing MODE to make to choose between the two installers -
SPICE (default) or OVIRT.

Some of the code in the Makefile was copied and adapted from
ovirt-wgt-installer.spec [1] and ovirt-guest-tools-iso.spec [2].
