Emil Maskovsky 6b98f44485 init: fix infinite loop on npos wrap with updated Seastar ...

Fixes parsing of comma-separated seed lists in "init.cc" and
"cql_test_env.cc" to use the standard `split_comma_separated_list`
utility, avoiding manual `npos` arithmetic. The previous code relied on
`npos` being `uint32_t(-1)`, which would not overflow in `uint64_t`
target and exit the loop as expected. With Seastar's upcoming change
to make `npos` `size_t(-1)`, this would wrap around to zero and cause
an infinite loop.

Switch to `split_comma_separated_list` standardized way of tokenization
that is also used in other places in the code. Empty tokens are handled
as before. This prevents startup hangs and test failures when Seastar is
updated.
