Motivation and Context

Resolve the warnings when running make checkstyle.

awk: cmd. line:1: warning: regexp escape sequence `\!' is not a known regexp operator
awk: cmd. line:1: warning: regexp escape sequence `\#' is not a known regexp operator

Description

The awk command used by the checkcheckbashisms target incorrectly
adds the escape character before the ! and # characters. This
results in the following warnings because these characters do not
need to be escaped.

awk: cmd. line:1: warning: regexp escape sequence
    `\!' is not a known regexp operator
awk: cmd. line:1: warning: regexp escape sequence
    `\#' is not a known regexp operator

Remove the unneeded escape character before ! and #.

Valid escape sequences are:

How Has This Been Tested?

Manually verified using gawk and mawk that the correct files
names were matched and no warnings were issued. Testing was
done on Fedora 33 and Ubuntu 20.04.

make checkbashisms
<no warnings printed>

Checklist:

The awk command used by the checkcheckbashisms target incorrectly
