Include ecf.filetransfer.httpclient5 in SimRel (#57)

This is to workaround:

- eclipse-equinox/p2#381

And to enable:

- eclipse-packaging/packages#81

in 2023-12 M3.

The Eclipse Platform is expected to contribute this for RC1
but including this from ECF allows us to start testing this
in 2023-12 M3
