bugfix: Fix failure caused by unset locale

In case, that VSPERF detects missing locale settings, it will
set language and encodding settings to default values specified
by configuration parameter DEFAULT_LOCALE.
Localized external commands with output parsed by VSPERF
are executed with modified locale to ensure correct VSPERF
function. Locale settings for such commands is specified
by configuration parameter DEFAULT_CMD_LOCALE.
