[PATCH 5.15 135/530] selinux: use "grep -E" instead of "egrep"

[Greg Kroah-Hartman]

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

commit c969bb8dbaf2f3628927eae73e7c579a74cf1b6e upstream.

The latest version of grep claims that egrep is now obsolete so the build
now contains warnings that look like:
	egrep: warning: egrep is obsolescent; using grep -E
fix this by using "grep -E" instead.
