server: always close http socket if responding with an error (issue6033)

It's possible for hgweb to respond _very_ early with an error if we're
catching certain types of errors. When we do, we need to tell the client
the socket is toast when there's a POST involved because otherwise there
can be lingering POST data on the socket that will confuse any future
requests on the socket. This manifested as a flaky failure on Linux in an
lfs extension test and a reliable failure on FreeBSD. With this patch
applied, test-lfs-serve-access.t now passes for me on FreeBSD.

# This script gets executed on container start. Its job is to set up
# the Mercurial environment and invoke the server.

# Mercurial can be started in two modes.
# If the MERCURIAL_SOURCE environment variable is set and it points to a
# Mercurial source directory, we will install Mercurial from that directory.
# Otherwise, we download the Mercurial source and install it manually.
