efi_loader: fix efi_ecpt_register()

Browse Source 
num_entries should be unsigned to avoid warnings. As the target field is
u16 we should use this type.

    lib/efi_loader/efi_conformance.c: In function ‘efi_ecpt_register’:
    lib/efi_loader/efi_conformance.c:30:33: warning:
    conversion to ‘long unsigned int’ from ‘int’ may change
    the sign of the result [-Wsign-conversion]
       30 |         ecpt_size = num_entries * sizeof(efi_guid_t)
          |                                 ^
    lib/efi_loader/efi_conformance.c:46:36: warning:
    conversion from ‘int’ to ‘u16’ {aka ‘short unsigned int’}
    may change value [-Wconversion]
       46 |         ecpt->number_of_profiles = num_entries;
          |                                    ^~~~~~~~~~~
