bitbake: bitbake-setup: dash support for init-build-env script

Being minimalist, dash does not support the (non-POSIX) feature of
passing an argument while sourcing a script. Like in
  . <some path>/oe-init-build-env <build dir>

With dash, one must use:
  set <build dir>       # puts <build dir> in $1
  cd <some path>
  . ./oe-init-build-env # can only be called from its directory in dash

To do this:
* Instead of a symlink to oe-init-build-env, keep a symlink to the
  directory containing it (called "oe-init-build-env-dir")
* Generate a init-build-env script that dash can source using the above
  snippet.
