Fix net-im/spectral build

Recent update to qtkeychain removed the need for the workaround
for lousy qtkeychain CMake configuration files -- and made the
workaround itself bad.

-Replace the linked libraries for QtKeychain by expanded ones.

-This is a workaround for QtKeychain installing a Config.cmake file
-that refers to libraries that are **not** expanded or in the
-default search path (e.g. glib). Without this expansion,
-we end up with -lglib in the final link line -- and no
-corresponding -L/usr/local/lib to make sure it is actually found.
