OvmfPkg/PlatformBootManagerCommonLib: Disable autoboot for EFI Shell

Setting the LOAD_OPTION_CATEGORY_APP flag for EFI Shell prevents the
boot loader from using it as a fallback if all other entries fail to
boot.

With a boot manager menu available, it can be annoying to enter the EFI
Shell directly, because from the menu, the user can try to boot again
(e.g. temporary network problem) or enter the shell/firmware config only
if necessary.
