devel/forge: Update to 0.3.0
* Add some ports to {BUILD|RUN}_DEPENDS. Currently they are indirect
dependency of this port and adding them to {BUILD|RUN}_DEPENDS
doesn't take any effect right now. But upstream specifies them as
dependency. Futhermore there are signs that dependency between the
ports that this port requires may change in the near future. And if
it really happens it may result in the issue that required port is
split from indirect dependency. So it is also intended as safekeeping.
* Adjust version range of dependency.
* Mark MAKE_JOBS_UNSAFE as parallel build fails if Emacs is built with
native compilation enabled.
