The efivars backend to pstore will not register if the efivarfs is
not available. The efivars sysfs interface was removed in Linux 6.0,
meaning efivarfs is now the only way pstore can write into EFI
variables. Making the dependency on the efivarfs explicit removes
a stumbling block when configuring a kernel with pstore.
