entity-manager: static library

Define static library entity_manager_lib without the main.cpp. This is
to facilitate unit testing down the line, since tests do have their own
entry point and would conflict with main() function in main.cpp.

By defining a library, a test does not have to compile parts of EM
again, and instead only links against the static library.

Tested: build/src/entity_manager/libentity-manager.a is built.
build/src/entity_manager/entity-manager is also built.
