logging fixup: shorter names for LOGGING_FILTER_* and LOGGING_CTX_*

In libosmocore, my patch was merged to master a bit too soon. To accomodate the
request for naming that matches the general "LOG" prefix instead of "LOGGING",
a fixup was committed to libosmocore. Adjust for that.

Original patch: change-id I5c343630020f4b108099696fd96c2111614c8067
The fixup: change-id I424fe3f12ea620338902b2bb8230544bde3f1a93

Change-Id: Ib2ec5e4884aa90f48051ee2f832af557aa525991
