Support reading 64 bit integers

Some sysfs *_input values may be bigger than 32 bits,
for example power values reported in microwatts.  As such,
read an int64_t value out of sysfs instead of just a uint32_t.
The D-Bus property that will hold the value is also the same
type, an int64_t.

Resolves openbmc/openbmc#2686
