cmake: remove $<LINK_ONLY:...> expressions from INTERFACE_LINK_LIBRARIES 

When torrent-rasterbar is built a static library, CMake supplies link
dependencies inside the LINK_ONLY generator expressions. But pkg-config
does not support such operational mode, and thus we can safely replace
those expressions with the library names. Closes #3354.
