Update our patches:
- drop patch 1, replaced by an upstream equivalent; adapt config
options and env accordingly,
- drop patch 2, applied upstream,
- rename patch 3
gdlib-config and net-snmp-config are only used when said support is
enabled (resp. CGI and SNMP), so no need to pass them unconditionally.
