Fix ResTable_config::CONFIG_* typo (MCC vs MNC)

In commit 08d5b8f, the ResTable_config::CONFIG_* enum was incorrectly
changed to assign the same value to both CONFIG_MCC and CONFIG_MNC:
    - CONFIG_MCC = 0x0001,
    - CONFIG_MNC = 0x0002,
    + CONFIG_MCC = ACONFIGURATION_MCC,
    + CONFIG_MNC = ACONFIGURATION_MCC,

This commit assigns CONFIG_MNC the value ACONFIGURATION_MNC, as
intended.

  change make noise when you're being quiet?
* Turn this off when system sounds are disabled during quiet hours
