Subject: [PATCH] Return something in non-void function (#70)

Return NULL in `background_thread`, as
the return type is `gpointer`.

Fixes this error in a `-Wall -Werror` build:

    cpdb-frontend.c: In function 'background_thread':
    cpdb-frontend.c:465:1: error: control reaches end of non-void function [-Werror=return-type]
      465 | }
          | ^
