Wrap output at 80 columns for poky-env-internal

The output of:

$ source poky-init-build-env

would wrap on 80 character terminals, making the output difficult to read.
Replace the somewhat clumsy repeated usage of "echo" with bash here documents,
limiting line length to 80 characters. The use of here documents simplifies this
by removing any leading commands or indentation from the output being generated.
A bash'ism should be acceptable here as poky-init-build-env already aborts if
the shell is not bash.
