promise/plugin/check_cpri_lock: Fix it to work ok with Amarisoft 2022

Old Amarisoft versions emit data that is different compared to what 640c0130 expected:

- there can be trailing spaces after /dev/sdrX@Y
  fix: adjust /dev/sdr regex
- there is empty line coming in the end that fas failing in l.split(':', 1)
  fix: ignore empty lines and make detection of : in the line more
       robust with reporting which line is not valid instead of just
       "ERROR not enough values to unpack (expected 2, got 1)"
- there is CPRI key instead of CPRI_option, and the data in both are different.
  fix: detect automatically whether it is CPRI_option or CPRI option that is present.
