Changed sFlowRcvrTimeout to a uint32_t to avoid time_t warnings
reported by Coverity. A uint32_t is more than large enough as
this is a (seconds) tick counter and OVS is not even using this.
Fixes: c72e245a0e2c ("Add InMon's sFlow Agent library to the build system.")

Note that this checkpatch reports an 'Improper whitespace
around control block' error on this patch + some warnings.
But I did not want to change the code style in this entire file.
