upas/fs: use memchr() instead of strchr() in hdrlen()

make sure we look for the end of the header within the
pointer range, and not accidentally read beyond hend.

also, messages are not null terminated, so this could
even go beyond the email data buffer.

get rid of mimeflag which was only used for some assert
checks.

take header length into account when comparing header
against ignored header strings.
