[PATCH 1/2] kernel32/tests: resource: Replicate muirct.exe behavior

[Jon Doron]

For some reason muirct.exe is aware of the opaque structure used by
BeginUpdateResource, it access the filename field of the opaque structure
during it's processing.

MS documentation for the muirct utility:
https://docs.microsoft.com/en-us/windows/desktop/intl/resource-utilities

Sample execution:
MUIRCT.EXE -c "ui.exe" -e "de-DE\ui.exe.mui"
