The stem of a request and of a relinked module name was cut at the first dot,
so a request for Engine.Render.prx that missed could load Engine.Core.prx.guest.prx.
Only the last extension is removed now, as the review of the stem lookup asked,
and the variant-names test requests a dotted name that must not load the sibling
fixture module.

A title asks for a module by its console name and the relinker names the
converted module after the ELF it was built from: Unity IL2CPP titles load
Media/Modules/<name>.prx and Media/Plugins/<name>.prx while the dump holds
<name>.elf.guest.prx, so sceKernelLoadStartModule failed with 0x80020002
and the title stopped 3 s after start. After the exact and the
case-insensitive <name>.guest.prx lookups miss, take the sibling whose stem
matches the request and ends with .guest.prx, shortest name first.
