exhibitor: Fix bugs in previous package

The previous package didn't build properly due to a bug in the build
script, and the nixos module didn't evaluate due to missing descriptions
in the options. This fixes both issues.

It also adds missing command-line options that weren't able to be set
and properly converts bools to the strings exhibitor expects.
