- Simplify error checking when using execute_process.
- Set BUILD_SHARED_LIBS to OFF when building dependencies.
This is normally not needed, but msgpack interprets an unset
BUILD_SHARED_LIBS to build a shared library, which is the opposite of
the cmake behavior.
- Move function check_lua_module to Util.cmake.
- Remove unnecessary code.
- Make variable naming more consistent

It only shortens the traceback a bit for when a module is not found
though, only removing the "(command line):1: in main chunk" (with
lua5.2).

This helps to figure out what the problem is, e.g. in my case I have
lua51-mpack installed to be used with luajit, but it is broken (missing
libmpack).
With this patch you get:

-- [/usr/bin/lua] The 'mpack' lua package is required for building Neovim
CMake Error at CMakeLists.txt:459 (message):
A suitable Lua interpreter was not found.
While this makes it more verbose for the expected error case ("module
'mpack' not found"), the behavior before this patch hides too much.
This is the old output:
-- Checking Lua interpreter /usr/bin/luajit
-- [/usr/bin/luajit] The 'mpack' lua package is required for building Neovim
-- Checking Lua interpreter /usr/bin/lua5.1
-- [/usr/bin/lua5.1] The 'mpack' lua package is required for building Neovim

-- [/usr/bin/lua5.2] The 'mpack' lua package is required for building Neovim
-- Checking Lua interpreter /usr/bin/lua
-- [/usr/bin/lua] The 'mpack' lua package is required for building Neovim
CMake Error at CMakeLists.txt:459 (message):
A suitable Lua interpreter was not found.
This is for when the whole configuration runs (i.e. after `make
distclean`), afterwards only one Lua interpreter gets checked only.

By default Neovim searched a Luajit instalation and linked against
the luajit library.
In practice Neovim only requires luajit to run the unit tests. All other
targets only require lua and the correct lua modules. This commit:
1. Remove the strict dependency on Luajit
2. Makes the unittest target depend on the lua 'ffi' module.
If the module is not available the target is not enabled
and a message is displayed.

This is in preparation for the next step, which is to find a suitable
lua interpreter, rather than just erroring when an interpreter is found
but doesn't have the necessary dependencies.
