Remove boost-python from BuildRequires
Fixed building on some systems.

Now ${Boost_LIBRARIES} variable is used instead of particular Boost library names. For example, these libraries have some different names on Ubuntu Trusty and Fedora.

Conflicts:
	CMakeLists.txt
Fixed building on some systems again.

Cocaine Runtime also links with some boost libraries. I forgot to fix it in the previous commit.
