Subject: freedreno/crashdec: handle section name typos

freedreno/crashdec: handle section name typos

The fixes tag isn't so much because it was incorrect before, but because
I'm going to send a kernel patch to fix the typo, and that will break
old crashdec.

Fixes: 1ea4ef0d3be ("freedreno: slurp in decode tools")
