Subject: [PATCH] pkgconfig: Use @CMAKE_INSTALL_LIBDIR@ variable

Use @CMAKE_INSTALL_LIBDIR@ variable instead of hardcoding "lib" as the libdir.
This is needed after 54bd57fb3b064c7f3d556b015e8f64fd8d234c19
(https://github.com/chaincodelabs/libmultiprocess/pull/79) which changed the
installation to sometimes install to "lib64".

This fixes error "ld: cannot find -lmultiprocess: No such file or directory" in
Bitcoin Core.

Also replace hardcoded "include" with @CMAKE_INSTALL_INCLUDEDIR@ for consistency.
