bin/utils: Ensure locale en_US.UTF-8 is available on the systemyocto-4.0.11yocto-4.0.102022-04.11-kirkstone2022-04.10-kirkstone2.0.112.0.10

Get rid of the duplicate code and add extra check that the
locale en_US.UTF-8 is available on the system. This new helper
method is now located right above the method filter_environment()
which sets LC_ALL environment variable to 'en_US.UTF-8'.
