runtime: repair gdb printing fix for 7.12, 8.{1,2,3}.1, 9.2
Hand-verified for listed gdb versions. Gdb (apparently)
changed the way it names certain Go types, and this change
broke the pretty-printer-activating code in runtime-gdb.py
runtime-gdb_test.go now checks channel, map, string, and slice
printing unconditionally (i.e., no opt-out for old versions).
Updates #39368.
