[meta-freescale] [base][PATCH 1/2] setup-environment: Add support for set distro

[Fabio Berton]

To run setup-environment you need to set one of distros listed on
supported distros using command like:

MACHINE=imx6qsabresd DISTRO=fslc-framebuffer source setup-environment build

Note that DISTRO is a required variable and won't be set if not defined.
