vsprintf.c: correct printing of a NULL device path
When printing '%pD' with a value of NULL we want to output
'<NULL>'. But this requires copying to buf. Leave this
to string16.
A unit test is supplied which relies on EFI support in the sandbox.
The development for EFI support in the sandbox is currently in branch
u-boot-dm/efi-working. The branch lacks commit 6ea8b580f06b ("efi_loader:
correct DeviceNodeToText for media types"). Ater rebasing the aforementioned
branch on U-Boot v2018.01 and adding 256060e4257a2 and this patch the test
is executed successfully.
Fixes: 256060e4257a2 (vsprintf.c: add EFI device path printing)
