purpose: OOS-build tests fail

Needed for server/pg_type.h header

CMake is shipped with broken PosgreSQL script in most distros.
I had to copy this script and patch it to properly support
new versions of PostgreSQL.

 * Install *.lua modules into ${DATADIR}/tarantool/1.5
    and *.so modules into ${LIBDIR}/tarantool/1.5
 * Fix default package.path and package.cpath
 * Install Lua headers to ${INCLUDE_DIR}/tarantool/1.5
 * Install config.h to ${INCLUDE_DIR}/tarantool/1.5
 * Add a new package - tarantool-dev (server development headers)
 * Use RPM Macroses in rpm.spec
 * Fix tarball generation for Debian
 * Use GNUInstallDirs.cmake to setup directories

packages.

 + memory leak in box.net.box (timeouted responses)
 + remote:ping() never throw exception
