zeromq: fix errors, use external libpgm, add devel

zeromq gets a makeover to fix build errors and to offer the devel
version. This has been tested with clang and llvm from XCode-4.4.1.

* Add a devel block
* Add a dep on libpgm, a new formula. The internal libpgm is b0rked
* Add a `do_config` function that gets run for devel or head builds.
* Add ENV.universal_binary for devel and head, it works.
* Add conditionals so that the manual lipo to UB is only for stable

Fixes #14210

Closes #14292.
