Heinrich Schuchardt 5f1ce1d4ca 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 6ea8b580f0 ("efi_loader:
correct DeviceNodeToText for media types"). Ater rebasing the aforementioned
branch on U-Boot v2018.01 and adding 256060e425 and this patch the test
is executed successfully.

Fixes: 256060e425 (vsprintf.c: add EFI device path printing)
