[PATCH] scripts/decode_stacktrace: Match basepath using shell prefix operator, not regex

From: Nicolas Boichat
Date: Sat May 18 2019 - 02:12:36 EST

The basepath may contain special characters, which would confuse
the regex matcher. ${var#prefix} does the right thing.

Fixes: 67a28de47faa8358 ("scripts/decode_stacktrace: only strip base path when a prefix of the path")

I'm not sure how people normally use this script, but this seems to break
even with a simple full path as parameter (e.g. /home/.../kernel/).
