5gmag-rt-modem.service can't find bladerf

[FMPandolfi]

Describe the bug On Ubuntu 20.04, when starting the modem as a daemon, it prompts an error saying bladerf_open_with_devinfo() returned -7 - No device(s) available. The modem service does not work properly and nothing is displayed in the wui. fivegmag-rt is already in the sudoers list and the command sudo setcap 'cap_sys_nice=eip' usr/local/bin/modem was prompted as well. If modem is run through the command line, though, everything works as intended.

To Reproduce Steps to reproduce the behavior:

1. Run 'sudo systemctl start 5gmag-rt-modem.service'

Expected behavior Modem can find bladerf SDR and start as intended.
