build: Move patches to <patch-repos> dir

Decouple main Makefile and repository patches by moving all Fuel
component patches to a subdir, <patch-repo>.

Proposed structure of <patch-repos> dir:
- patch-repos/*.patch are intended for <fuel-main> git repo;
- patch-repos/build/repo/<fuel-module>/*.patch are intended for
  <fuel-module>, e.g. "fuel-nailgun";

Full list of Fuel submodules supported by this mechanism at [1].

While at it, replace all occurences of </tmp/fuel-main> with
<FUEL_MAIN_DIR> in main Makefile and rewrite a few git/make calls
to use the "-C" arg.

NOTE: `git -C` is available starting with git 1.8.5.

-Subject: repo mirror: Allow multi-arch local mirrors
-
-This patch allows specifying multiple architectures via UBUNTU_ARCH in
-form of a list of space separated architectures. The first architecture
-in the list is considered primary and will be used for building all the
-deb packages by fuel-main. Additional architectures are added to allow
-targets of other architectures to use the mirror.
-NOTE: this imposes a requirement that all packages built are arch
-independent (which is true so far).
