obmc-flash-bmc: Ignore fw_printenv return code

If an environment variable doesn't exist, fw_printenv returns 1
(error). With the addition of "set -eo pipefail" to the
obmc-flash-bmc script, this error causes the service that sets
the priorities to fail:

 witherspoon systemd[1]: Starting Set U-Boot environment variable...
 witherspoon obmc-flash-bmc[3883]: ## Error: "66089bab" not defined
 witherspoon systemd[1]: obmc-flash-bmc-setenv@66089bab\x3d0.service: Main process exited, code=exited, status=1/FAILURE
 witherspoon systemd[1]: Failed to start Set U-Boot environment variable.

Ignore the return code instead, the variable will be empty
if fw_printenv doesn't return a value.
