[PATCH v2 6/8] Makefile: Add a target for building capsules

[Sughosh Ganu]

Add a target for building EFI capsules. The capsule parameters are
specified through a config file, and the path to the config file is
specified through CONFIG_EFI_CAPSULE_CFG_FILE. When the config file is
not specified, the command only builds tools.

Changes since V1:
* Call the mkeficapsule utility with the cfg-file parameter when
  building capsules via the config file.
