EFI firmware refuses to allocate memory of type
GRUB_EFI_CONVENTIONAL_MEMORY, because that indicates a block of
available memory that other allocations (or the OS) would then step on.
Map GRUB_MEMORY_AVAILABLE to GRUB_EFI_LOADER_CODE instead.

* grub-core/mmap/efi/mmap.c (make_efi_memtype): Map
GRUB_MEMORY_AVAILABLE to GRUB_EFI_LOADER_CODE rather than
GRUB_EFI_CONVENTIONAL_MEMORY. EFI firmware refuses to allocate
memory of type GRUB_EFI_CONVENTIONAL_MEMORY, because that
indicates a block of available memory that other allocations (or
the OS) would then step on.
