btrfs-progs: Improve static building and installation

Browse Source 
This commit improves the static-only building of btrfs-progs, and adds
support for installing the static only tools:

 - It now ensures that all programs are built statically, not only a
   small subset of them, by defining 'progs_static' from the existing
   'progs' variable.

 - It changes the order of libraries in the btrfs-%.static rule so
   that -lpthread (part of STATIC_LIBS) appears *after* the '$($(subst
   -,_,$(subst .static,,$@)-libs))' logic, which brings in
   -lcom_err. This is needed because libcom_err.a uses the semaphore
   functions, which are available in the pthread library.

 - Adds the necessary rules to generate the btrfsck.static link and
   btrfstune.static binary.

 - Adds an 'install-static' target to install the static
   binaries. Note that they are renamed to not carry a '.static'
   suffix.
