waffle: Fix build location of libwaffle_static.a
waffle: Fix build location of libwaffle_static.a

I intended to place libwaffle_static.a into ${CMAKE_BINARY_DIR}/lib,
which is the same directory into which libwaffle.so is placed. However,
I failed at CMake-foo for static libraries.  The
LIBRARY_OUTPUT_DIRECTORY property is ignored for static libraries.
Instead, the ARCHIVE_OUTPUT_DIRECTORY property must be used.
