Support to build storage commands in libipmi20

Currently, the storage commands only is built in the libdynamicsensor
library. To build those commands, we have to enable dynamic-sensor
option which makes sensor commands are built too.

To allow compiling storage commands w/o sensor commands, this commit
adds 'dynamic-storages-only' option to request to build storage commands
in libipmi20 library.

Tested:
  1. Disable dynamic-sensor option and enable dynamic-storages-only
     option.
  2. Built the openBmc image and flash to the board.
  3. Request to read/write FRU device via ipmitool.
     All of request work well.
  4. Request to read SEL list.
     Display list of SEL logs.
