runtime: update skips for TestGdbBacktrace

Browse source 
We encountered a new type of "no such process" error on loong64, it's like this
"Couldn't get NT_PRSTATUS registers: No such process.", I checked the source code
of gdb, NT_PRSTATUS is not fixed, it may be another name, so I use regular
expression here to match possible cases.

Updates #50838
Fixes #74389
