Add a separate script to build the memstick.img and the

mini-memstick.img with UEFI support.

As the comments in the file suggest, 1) there must
be existing ${.OBJDIR}/usr/src/release/{release,bootonly};
2) TARGET/TARGET_ARCH must be amd64; and 3) it must be
a vt(4)-enabled kernel with vt_efifb (*not* vt_vga).

This script is not hooked into release/Makefile in any way
until further testing is complete.

+# This script generates a "memstick image" for UEFI-capable systems.
+#
+# Prerequisites:
+#  - 'make release'
+#  - KERNCONF *must* be VT (or vt_efifb(4) compiled into the kernel)
+#
+# Note:  This only works for amd64, because i386 lacks the EFI boot bits.
+#
+# Usage: make-memstick.sh <directory tree> <image filename>
