CI: migrate RFSim4G to acamas machine

• Testing on acamas machine done in test pipeline (duplicate of main RFSim4G pipeline): https://jenkins-oai.eurecom.fr/job/RAN-RFSim-Test-5G-Acamas/
• Sample run:
  • https://jenkins-oai.eurecom.fr/job/RAN-RFSim-Test-5G-Acamas/36/ --> OK
  • https://jenkins-oai.eurecom.fr/job/RAN-RFSim-Test-5G-Acamas/37/ --> OK
  • https://jenkins-oai.eurecom.fr/job/RAN-RFSim-Test-5G-Acamas/38/ --> OK

Note: set BUILD-ONLY label, because modifications are only related to RFSim4G test - test on acamas needs to be triggered manually
