Enable environment variable deletion from obmc-flash-bmc-setenv@.service
This commit extends the functionality of obmc-flash-bmc-setenv@.service,
which calls upon the obmc-flash-bmc script to set an environment
variable.
When working with environment variables in the shell, one can set OR
clear a particular variable using the fw_setenv command. This commit
expands the functionality of the service file to match.
If a name-value pair is specified, this script will set the environment
variable as given. If a name is supplied with no value, the environment
variable with that name will be cleared.
