[SCSI] fcoe, libfc: add libfcoe module

Just sets up build environment for libfcoe module towards a
libfcoe library for libfc LLDs using FCoE as libfc transport.

Common library code to libfcoe is added in next patch.

Also, updated MODULE_LICENSE from "GPL" string to "GPL v2" for
libfc, libfcoe and fcoe modules to accurately match the licenses.
