main: set LC_NUMERIC to C

Browse source 
The webrtc backend of module-echo-cancel uses sscanf() to parse floating
point numbers from module arguments, which didn't work when the locale
used a comma for the decimal point. Setting the LC_NUMERIC locale
variable to C makes the pulseaudio process use a period as the decimal
point regardless of the user's locale configuration.
