Title: Fix a memory leak from use of realpath() in HTTP request processing.

realpath() returns a heap-allocated buffer if given NULL for the destination buffer.
This must be freed by the caller; dump1090 does not do this.

Instead of worrying about freeing it, take the simpler approach of just providing a
stack-allocated destination buffer.
