secvar/backend: use endian-aware types in edk2.h

Recently we had an issue where we did the following:

uint16_t year = le32_to_cpu(timestamp->year);

This is wrong and will break on BE. However, we didn't catch this
with sparse because there was a whole slew of warnings.

The reason for the slew of warnings is that we didn't annotate the
types that store little-endian specific data in edk2.h.

Provide the appropriate annotations.

We now get a single sparse warning for the file, which correctly
identifies the issue:

edk2-compat-process.c:374:46: warning: incorrect type in argument 1 (different base types)
edk2-compat-process.c:374:46:    expected restricted leint32_t [usertype] le_val
edk2-compat-process.c:374:46:    got restricted leint16_t const [usertype] year

We do lose the signedness of efi_time->timezone, but that's probably OK:
we never use the timezone anyway and the comment above the data structure
makes the signedness pretty clear.
