[OE-core] [PATCH v4 1/7] bitbake.conf: support for merged usr with DISTRO_FEATURE usrmerge

[Amarnath Valluri]

A new configuration variable ${root_prefix} added, which shall be used by all
base_{lib,bin,sbin}dir variables. When usrmerge DISTRO_FEATURE is enabled
${root_prefix} points to ${exec_prefix} otherwise to ${base_prefix}
