mgw: Make check of duplicated LCO fields case insensitive

Otherwise it would not catch a duplicate if first the param is
introduced in upper case and later in lower case, or the other way
around.

MGCP RFC3435 (https://tools.ietf.org/html/rfc3435) states almost all
text has to be handled in a case-insensitive way, except SDP parts.
