[#3666] kea-admin lease-upload: write SQL statements to file

Avoids "Argument list too long".

Also considerably speeds up the lease upload. The slowdown was
noticeable for large number of leases, where for each lease, the whole
set of statements added up to that point had to be printed in order to
append another SQL statement. This is no longer the case since the SQL
statement is appended to a file.
