verify_pefile: relax wrapper length check
The PE Format Specification (section "The Attribute Certificate Table
(Image Only)") states that `dwLength` is to be rounded up to 8-byte
alignment when used for traversal. Therefore, the field is not required
to be an 8-byte multiple in the first place.
Accordingly, pesign has not performed this alignment since version
0.110. This causes kexec failure on pesign'd binaries with "PEFILE:
Signature wrapper len wrong". Update the comment and relax the check.
