[PATCH v4 4/6] tag.c: Replace varialbe name for readability

[santiago@nyu.edu]

From: Santiago Torres <santiago@nyu.edu>

The run_gpg_verify function has two variables size, and len. This may
come off as confusing when reading the code. We clarify which one
pertains to the length of the tag headers by renaming len to
payload_length.

	Note: this used to be part of the previous patch on v3. I moved the
renaming part to a single patch to simplify the review.
