Newer versions of awk spit out these fun warnings:
awk: ../lib/raid6/unroll.awk:16: warning: regexp escape sequence `\#' is not a known regexp operator
As commit 700c1018b8 ("x86/insn: Fix awk regexp warnings") showed, it
turns out that there are a number of awk strings that do not need to be
escaped and newer versions of awk now warn about this.
Fix the string up so that no warning is produced. The exact same kernel
module gets created before and after this patch, showing that it wasn't
needed.
