Generate a pkg-config support file #140

Browse Source 
We pull the version out of libdeflate.h into the
Makefile, and then sed a few macros out of the new
file libdeflate.pc.in. Set the necessary Cflags
and Libs (CFLAGS and LFLAGS) based off compile-time
definitions. Depend on the Makefile to pick up
version changes. Update uninstall target.
