logging-gsmtap: send only basename of source file
GSMTAP doesn't have a lot of space for the source file name. It is better to
send only the basename of the file, because only the first bit of a long path
may not convey the source file at all, needing guess work from the line number.
Before: "Source File Name: ../../../../src/libosmocore/src"
After: "Source File Name: telnet_interface.c"
