Subject: [PATCH] Fix shader corruption on OpenBSD

OpenBSD's sed (and possibly other platforms') interprets `\r` as a
literal `r` rather than a carriage return, which leads to all `r`
letters being stripped from the shaders' source.

This fixes the issue by using the POSIX-compliant `tr -d '\r'` to remove
carriage returns.

Thanks to @ryan-sg for reporting the issue
