vici: Support ruby gem out-of-tree builds

Referencing $(srcdir) in the gemspec is not really an option, as "gem build"
includes the full path in the gem, so we need to build in $(srcdir). As there
does not seem to be a way to control the output of "gem build", we manually
move the gem to $(builddir) in OOT builds.
