[Buildroot] [PATCH v4 6/9] autobuild-run: set LC_ALL=C to not use locale settings of host machine

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

If the host machine running autobuild-run happens to have set a
non-English locale, the error messages will be displayed in that
language too. For public results like those generated in the Buildroot
autobuilders, this is a problem.

Therefore, set LC_ALL to a fixed locale (C) at the beginning of the script.
