Allow EAGAIN failures

Certain devices are known to return EAGAIN failures when read
too frequently, so be tolerant of them.

On startup, the code will retry for up to a second to get a good
first reading, and then in the main loop the code will just stick
with the current value if it fails that way.

Resolves openbmc/openbmc#2038
