shim: Properly generate absolute paths from relative image paths
The generate_path_from_image_path() doesn't properly handle the case when
shim is invoked using a relative path (e.g: from the EFI shell). In that
function, always the last component is stripped from absolute file path
to calculate the dirname, and this is concatenated with the image path.
But if the path is a relative one, the function will wrongly concatenate
the dirname with the relative image path, i.e:
Shell> FS0:
FS0:\> cd EFI
FS0:\EFI\> BOOT\BOOTX64.EFI
Failed to open \EFI\BOOT\BOOT\BOOTX64.EFI - Not found
Failed to load image \EFI\BOOT\BOOT\BOOTX64.EFI: Not found
start_image() returned Not found
Calculate the image path basename and concatenate that with the dirname.
