ttcn3-pgw-test: configure the 'ogstun' device for open5gs-upfd

Unlike osmo-ggsn, open5gs-upfd does not configure the tun interface
itself.  All IPv4/IPv6 addresses must be assigned manually.  This
is exactly why both PGW_Tests.TC_createSession_ping4[_256] fail:

  [sock] ERROR: ogs_write() failed (5:Input/outputerror) (../lib/tun/tunio.c:84)
  [upf] WARNING: ogs_tun_write() failed (../src/upf/gtp-path.c:448)

Take Harald's setup.sh from open5gs-master and execute it in the
container running open5gs-upfd.  This fixes the ogs_write() errors.

open5gs-master: remove both setup.sh and pgw.sh

Having these scripts makes no sense anymore, because:

  * setup.sh was moved to ttcn3-pgw-test,
  * pgw.sh runs non-existing open5gs-pgwd.
