Titles that list libSceUsbd.prx as a needed module stop in the
startup stub with "Failed to load module: libs\libSceUsbd.prx"
(GetLastError 126), even when they import no function from it.
Add libSceUsbd with an Export.cpp that contains only APS5_DUMMY_FUN,
like libkernel_sys, libkernel_web, libSceAgcVsh, libSceAjm and
libSceNgs2. The module now loads, exports no sceUsbd function and
guesses no signature, so a title that does import one still stops
with "FAIL: unresolved ELF import" for that NID.
