[dev] Support symlinked keyfiles (pkgxdev#932)

Fixes pkgxdev#890

Bump to libpkgx 0.16

* Will fix some errors due to invalid pantry parsing
* Removes platform specific moustaches devenvs
  * these weren't documented so even though this is strictly a breaking change I would be willing to risk the tea protocol slash consequences for it in a tea protocol future
  * there is potential utility in platform/arch being there so we should propose a proper addition
* Fix CD
