flashrom spills out "Reading flash... SUCCESS" and so on to stdout. This
affects scripts calling to "cgpt". So this CL sets stdout to CLOEXEC
before exec'ing flashrom. It still leaves stderr and stdin unclosed.

TEST=cgpt show /dev/mtd0 2>/dev/null will not show any unnecessary text

This CL adds a "cgpt_wrapper" binary that will forward to "cgpt" binary
as needed to transparently support NAND.
The idea is that if we are working with an MTD device, this binary will
exec out to "flashrom" to read in the GPT section, then exec out to the
actual "cgpt" binary to work on that file, and finally write it back
with "flashrom".
This CL introduces a make target "install_mtd" to install this wrapper.
The corresponding ebuild should use this make target when "mtd" USE flag
is on.
