Not sure that /var/cache is the best place, since according to the FHS, it may
be emptied by the system administrator. /var/cache is mainly for storing data
which take a long time to be computed, but can be regenerated by the
application if needed.

Maybe /var/lib/dhcpcd? According to FHS:
"[The /var/lib] hierarchy holds state information pertaining to an application
or the system. State information is data that programs modify while they run,
and that pertains to one specific host.[...]. State information is generally
used to preserve the condition of an application (or a group of inter-related
applications) between invocations and between different instances of the same
application. State information should generally remain valid after a reboot,
should not be logging output, and should not be spooled data [...]". This is
close to what a lease is (dbdir is primarily where dhcpcd stores leases).
