[klibc] [PATCH - RFC] Move initramfs configuration to "General setup"

[Sam Ravnborg]

At present the configuration items for initramfs is located in:
Device drivers | Block Drivers | xxx

This is maybe not the most natural place to have it.
So with the following patch it is moved below "General setup",
and relevant config items are collected in a file with a new
home in usr/.

The original reason why I looked into this is the upcoming merge of klibc
and I missed a good place to include the KLIBC relevant config options.
With the Kconfig file added to usr/ is will be a simple menuconfig
in here for all the KLIBC relevant config options.

Any comments?
