Piotr Jastrzebski 2aaf81bf7c dht: Exclude -2^63 value from get_random_token

-2^63 is a value reserved for min/max token boundaries and shouldn't be used for
regular tokens. This patch fixes get_random_token to never create token with
value -2^63. On the way dht::get_random_number template method is removed
because it was exclusively used by get_random_token.

Also use uniform_int_distribution with int64_t instead of uint64_t by using
correct constructor parameter that guarantees values between -2^63+1 and 2^63-1
inclusively.

Tests: unit(dev)

Fixes #6237.
