lib/vdso: use "grep -E" instead of "egrep"

Browse source 
commit 8ac3b5cd3e upstream.

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