Build tz-launcher from package root dirsubmit/tizen_common/20140618.103325

Add a Makefile.am and a configure.ac in the package root dir in order to
be able to build tz-launcher without having to cd in the subdirectory in
the spec file.

Rename directory tz-launcher to src.

Also remove executable bit from license file src/COPYING.
