Subject: [PATCH] Add support for UEFI operating systems returned by os-prober

os-prober returns UEFI operating systems in the form:

path:long-name:name

where path is the path under the EFI directory on the ESP. This is in
contrast to legacy OSes, where path is the device string. Handle this case.
