build: use sed instead of AC_SUBST() to generate man/common.ent

Otherwise, substitions are not properly expanded.

For example

- "AC_SUBST(nmrundir, '${runstatedir}'/$PACKAGE, [NetworkManager runtime state directory])"
  gives ${runstatedir}/NetworkManager/resolv.conf

- "AC_SUBST(nmrundir, "${runstatedir}/$PACKAGE", [NetworkManager runtime state directory])"
  gives ${prefix}/var/run/NetworkManager/resolv.conf

(cherry picked from commit 4de6f603e3)
