[PATCH xserver] tests: Add missing -l dependencies

[Mihail Konev]

It is worth noting, that it was not ld.bfd that scanning in one
direction, but rather ld.gold ignoring the --as-needed flag
(which, at the time of testing, was built-in into gcc -dumpspecs).

Reproducible-by: make CC=" gcc -Wl,--as-needed "

Corrects: b1a69863 ("tests: shuffle around the linking order")
Signed-off-by: Mihail Konev <k.mvc at ya.ru>
---
Tested with all --enable-... except for:
  werror, strict-compilation, config-hal, xselinux, xwin, xquartz

"make -C test tests" works, only Xdmx fails to link :)
