libmicrohttpd: upgrade to 0.9.54

This version of libmicrohttpd includes facilities
for upgrading connections to websockets.
Adopting it in advance allows to remove a patch
specific to AGL needed by app-framework-binder.

The patch applied here is a backport from the
upstream (see https://gnunet.org/git/libmicrohttpd.git/
commit b4216c60fdb5b48f6cfec416301fc63a1167e6cd).

+Subject: [PATCH] Check response existence on upgrade
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When a connection upgrade is requested and when the
+request sent an error reply, the response is most of
+the time already sent when the test on
+connection->response->upgrade_handler is made, leading
+to dereferencing NULL.
+
+Two possibilities exist:
+
+  NULL == connection->response || NULL == connection->response->upgrade_handler
+
+or
+
+  NULL != connection->response && NULL == connection->response->upgrade_handler
+
+The first is prefered because it is probably safer to close the connection
+in that case.
+
+Upstream-Status: Accepted [https://gnunet.org/git/libmicrohttpd.git/commit/?id=b4216c60fdb5b48f6cfec416301fc63a1167e6cd]
