osmo-gsm-tester: Add missing srsLTE dependencies (soapy)

Currently srsLTE trials link against soapySDR library to have LimeSDR
support. We need to move installation of those new packages further
below in the Dockerfiler because that lib version is only available with
osmocom repositories (which were added at a later point in the file).
