device: Mark fingers names array as const and use unique name

Browse Source 
With the stronger warnings enabled when building with meson, we get a
warning for all the fingers definitions:

  ../src/device.c:38:24: warning: initialization discards ‘const’ qualifier
  from pointer target type [-Wdiscarded-qualifiers]
    38 |  [FP_FINGER_UNKNOWN] = "unknown",

As the `fingers` array name was shadowed in another file:

  ../src/device.c:1000:11: warning: declaration of ‘fingers’ shadows a
  global declaration [-Wshadow]
    1000 |   GSList *fingers, *finger;
