[Bug 1965972] [NEW] shim doesn't boot boot entries without spaces/zero characters in optional data

[Julian Andres Klode]

Public bug reported:

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
