scripts: build-combined-fwbundle: use semantic version in filename

Use the semantic version in the filename of the firmware bundle rather
than the quad-dotted versioning scheme historically used.

Going forward, release candidate firmware packs will have names like
fw_pack-18.3.0-rc1.fwbundle rather than fw_pack-18.3.0.1.fwbundle, and
final releases will have names like fw_pack-18.3.0.fwbundle rather than
fw_pack-18.3.0.0.fwbundle.
