fix(inspur): strip iBMC firmware build-timestamp suffix

A second NF5280M6 BMC-dump/live-CD pair showed RESTful version info
firmware versions carrying a build stamp ("08.05.01 (02/21/2024
16:51:27)") the live-CD does not, which churns a FIRMWARE_CHANGED event
on every source switch. cleanFirmwareVersion strips a trailing " (...)"
so BIOS/BMC match the bare live-CD version. See ADL-064 amendment.
