[OE-core] [oe-core] Add option to oe-buildenv-internal script to change bitbake location.

[Philip Balister]

Having bitbake inside the oe-core is annoying to some people. This commit
adds a second option to the oe-init-build-env script.

Run like this:

. ./oe-init-build-env ../build ../bitbake

for example. Without the second option, the old behavior is preserved.
