Bug Description

shim ignores any optional data passed that does not contain a space or nul character.

bad fallback csv entry:

shimx64.efi,Ubuntu with kernel 5.4.0-1072-azure-cvm,\kernel.efi-5.4.0-1072-azure-cvm,Ubuntu entry for kernel 5.4.0-1072-azure-cvm

good csv, with additional space:

shimx64.efi,Ubuntu with kernel 5.4.0-1072-azure-cvm,\kernel.efi-5.4.0-1072-azure-cvm ,Ubuntu entry for kernel 5.4.0-1072-azure-cvm

given how cryptic optional data parsing in shim, I am not surprised.
last time I tried to figure out how to make it work, I failed.
so somewhat this sounds right that a space helps.
