[gdb] Fix 'not in executable format' error message
With trying to load a non-executable file into gdb, we run into PR26880:
...
$ gdb -q -batch test.c
"0x7ffc87bfc8d0s": not in executable format: \
file format not recognized
...
The problem is caused by using %ps in combination with the error function
(note that confusingly, it does work in combination with the warning
function).
Fix this by using plain "%s" instead.
Tested on x86_64-linux.
