scripts: coccicheck: use "grep -E" instead of "egrep"

Browse Source 
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 up by moving the vdso Makefile to use "grep -E" instead.
