Update nvramtool to git HEAD as of today using local distfile.

No upstream change summary, but the old version no longer worked with
modern coreboot.

Distfile created from a full clone of the coreboot tree with below script;
#!/bin/sh
cbver=`git describe`
cbobj=`git ls-tree origin/master util/nvramtool|awk '{print $3}'|cut -c 1-7`
distname=nvramtool-"$cbver"-"$cbobj"
git archive -o /tmp/"$distname".tar.gz --prefix="$distname"/ "$cbobj"
Updated sysutils/nvramtool to 0pre20131209
Update flashrom to 0.9.7.

changes since 0.9.5:

==User interface changes==
* The -p/--programmer parameter is now mandatory for all operations that access the programmer/chip.
*: Previously there was a default programmer selected at build time. This was convenient for most users, but created a danger for others that increased with the number of platforms and programmers supported, namely that they get used to a default programmer that later changes when they use another binary. It is very easy to brick a mainboard in case you do not notice you are writing its firmware instead of a device attached to an external programmer. The disadvantage is of course that many users have now to add '''-p internal''' to the command line when they want to do ''the obvious'' and flash their mainboards.
* It is now possible to let flashrom create log files directly (by using the new -o/--output option).
* flashrom now checks for duplicate -i/--image arguments (which are used together with layout files).

==New major user-visible features==
* Programmer support:
** new driver ''ponyprog'' for hardware similar to SI Prog
** native SPI AAI write support to the Dediprog SF100 driver
* Support for new chips:
** Atmel AT49F040
** Eon EN25QH32
** Eon EN29LV640B
** GigaDevice GD25QXX
** Numonyx N25Q064
** PMC Pm39LV512

==Infrastructural improvements and fixes==
* The dummy programmer got support for SFDP and now has a dedicated status register.
* Various minor refactorings of SPI-related code.
* The code generating the list of supported hardware for the wiki has been improved.
* Many exit() calls have been replaced by proper error handling.
* I/O permissions are now released automatically on shutdown.
* Preliminary work on Winbond W836xx and ITE IT8707F/IT8710F detection.
