Subject: [PATCH] scripts/decode_stacktrace: match basepath using shell prefix
operator, not regex
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")
