http-backend: allow empty CONTENT_LENGTH

According to RFC3875, empty environment variable is equivalent to unset,
and for CONTENT_LENGTH it should mean zero body to read.

However, unset CONTENT_LENGTH is also used for chunked encoding to indicate
reading until EOF. At least, the test "large fetch-pack requests can be split
across POSTs" from t5551 starts faliing, if unset or empty CONTENT_LENGTH is
treated as zero length body. So keep the existing behavior as much as possible.

Add a test for the case.
