Bring back the old CyanAlarm alarm tone

For almost two months now I've been wondering why my phone's alarm clock
has lost much of its effectiveness. Today the reason finally hit me: the
CyanAlarm tone had been sneakily replaced in commit ID
dbb169ad9c33bdc392b47f7a1bdef3843eff9ab2!

Although the new tone is certainly more pleasant to listen at and
doesn't cause any heart attacks, it is less effective for heavy
sleepers like myself. This commit brings back the old CyanAlarm
version with the new (tentative) name "Nuclear Launch".

Rather than having to maintain out of tree changes, it is often
easier to maintain a hiearchy of changes, starting with the vendors
common config file. From there, inheriting products can pick up a base
and start to add or remove certain bits from it, making use of the
BOARD_SEPOLICY_* functions documented in external/sepolicy/README.
