debuginfo: Fix gdbr-check expectations of formatting

This was a largely automated process, driven by the hack of a shell
script below.  The process to generate the patch was to repeatedly run
the script until the changes reached a fixed-point.

```bash

set -euo pipefail

O=$(mktemp)
./x.py test src/test/debuginfo 2>&1 | tee $O || true

awk '
function escape_pattern(pat,   safe) {
  safe = pat
  gsub(/[][^$.*?+{}\\()|]/, "\\\\&", safe)
  return safe
}

BEGIN { p = 0; n = 0; }

/---- \[debuginfo-gdb\]/ {
	if (p == 1) {
		printf("%s|%s|%s\n", src, error, expected);
	}
	src = $3;
	p = 1;
	n = 0;
	name = "";
}

n == 1 && $0 ~ name {
	expected = $0;
	n = 0;
}

/error: line not found in debugger output/ {
	error = substr($0,43);
	split(error, pieces);
	name = escape_pattern(pieces[1]);
	print "Found " name " in: " $0 > "/dev/stderr"
	n = 1;
}

END { printf("%s|%s|%s\n", src, error, expected); }
