Because we do not use "execvp", "cgpt.bin" is not resolved to the same
directory as "cgpt". So we need to resolve the original command to its
absolute path first, then append ".bin" to it.
BUG=None
BRANCH=None
TEST="cgpt" no longer fails.

We always wrote back the rw_gpt file to NOR flash. This operation is too
slow. This CL compares if the original file has been changed by cgpt.bin
before writing the file back to NOR.
BUG=None
BRANCH=None
TEST=/usr/bin/cgpt show /dev/mtd0 now does not write back to NOR

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.
