libs: Don't allow static libraries to be built

Static libraries have no namespacing, so our "private" symbols become
global. This results in functions like os_create_anonymous_file() crashing
into functions of the same name in multiple projects.

Since our test suite fails for static builds already, it's probably a clear
indication that they're not well tested - so let's just force everything to
be shared instead of trying to fix up static support.
