updated SH4ZAM's port metadata.

[gyrovorbis]

Just some minor tweaks to SH4ZAM's Makefile and pkg-descr for beautification. Also changed the PORTVERSION from a made up point release to just "latest," as it's sitting on the tip of master.

latest as version breaks the testing done for versions in the scripting. Easy fix would be to just do 1.0.1 or something, but could also have the version comp work with it. I think in that case it would be something like 'if it's non-numeric, and different always update'

sh4zam is already installed and is latest version. Exiting.
