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).
