library/DIAMETER_Templates: fix flags in AIR templates

According to RFC 6733, section 3 "Diameter Header", if the 'R' bit
is set, the message is a request.  If the 'P' bit is set, the
message may be proxied, relayed, or redirected.

ts_DIA_AIR is a template for Authentication Information *Request*,
so the 'R' bit must be set.  Also, let's allow this message to be
proxied, relayed, or redirected by setting the 'P' bit by default.

In tr_DIA_AIR, do not match all command flags, just ensure that
the message is a request.  Other flags do not matter.
