xpp: FXS: mwi and search_fsk fixes

* We must not block PCM during from 'search_fsk_pattern' channels.
* We must vmwi_search() not only on FXS_LINE_POL_ACTIVE, but also during
  'neon_blinking' -- so we notice the message to turn it off.
* Also added 'search_fsk_pattern' and neon_blinking to /proc/.../fxs_info
