[OE-core] [PATCH v2] kernel-yocto: Disable ANSI escape codes from git branch

[Matt Fleming]

From: Matt Fleming <matt.fleming at intel.com>

'git branch' may use ANSI escape codes in its output (to provide colour)
which doesn't play well with commands expecting pure plain text, e.g.

    fatal: '^[[31mmaster^[[m' is not a valid branch name.

Use the --no-color option to ensure all branch names are plain text.

v2: Make the minimum change necessary to disable the escape codes per
    Bruce's suggestion.
