deskutils/bijiben: Add generated biji-marshalers.h to libbiji dependency sources (D29353)

The meson manual states that

Each target that depends on a generated header should add that
header to it's sources, as seen above with libfoo and myexe. This
is because there is no way for Meson or the backend to know that
myexe depends on foo.h just because libfoo does, it could be a
private header.

Since biji-marshalers.h is included by the libbiji public header
libbiji.h, it must be added as a source to all targets that depend
on libbiji. This can be done by adding it to the sources of
libbiji_dep.

This should unbreak the build with samurai.
