build: Fix libeap_peer.a build

The install target at the beginning of src/eap_peer/Makefile was
confusing make about the build rules for libeap_peer.a and overriding of
the install target between src/eap_peer/Makefile and src/lib.rules was
breaking installation of dynamic EAP peer *.so files.

Fix this by lib.rules defining a default for the install target so that
src/*/Makefile can override that and by moving the install target for
eap_peer to the end of the Makefile.
