[PATCH v3 2/3] populate_sdk_base.bbclass: Improve debugging capabilities for SDK installer

[Jason Wessel <jason.wessel@windriver.com>]

After having to debug the SDK installer a few times in
addition to the relocation code the following patch was created
to improve the capabilities around debugging the SDK installer.

1) Add a verbose mode -D which set a set -x to see what
   the SDK installer is doing.

2) Add a mode -S to save the relocation scripts for the purpose
   of debugging them in conjunction with -D

3) Add a mode -R to not execute the relocation scripts for the
   purpose of debugging the relocations.
