libradius: Fix attribute length validation in rad_get_attr(3)

The length of the attribute header needs to be excluded when comparing
the attribute length against the length of the packet.  Otherwise,
validation may incorrectly fail when fetching the final attribute in a
message.

Fixes: 8d5c78130 ("libradius: Fix input validation bugs")

(cherry picked from commit 6bb5699d2b59491097bc21ffa3c097cdd4853f89)
