[meta-freescale] Trivial bug

[Timur Aydin]

Hi,

I found a very trivial bug in the setup-environment script. When the 
script copies over files from /sources/base/* and sets the updated flag, 
it writes out a message:

"The project root content has been updated. Please run bash again."

Note that "bash", which is the value of $0 when the script is sourced.

It should probably just say "Please run the script again".
