data mover daemon RPM build does not contain github commit hash

[NateThornton]

The RPM build does not provide the correct GitHub commit hash, so the daemon is reporting v0.0.1-unknown

When using the build-daemon make target, the commit hash is loaded from git

nnf-dm/Makefile

Lines 123 to 126 in d5df11f

	build-daemon: COMMIT_HASH = $(shell git rev-parse --short HEAD)
	build-daemon: PACKAGE = github.com/NearNodeFlash/nnf-dm/daemons/compute/server/version
	build-daemon: manifests generate fmt vet ## Build standalone nnf-datamovement daemon
	GOOS=linux GOARCH=amd64 go build -ldflags="-X '$(PACKAGE).commitHash=$(COMMIT_HASH)'" -o bin/nnf-dm daemons/compute/server/main.go

If this fails, the default value is "unknown"

nnf-dm/daemons/compute/server/version/version.go

Line 30 in d5df11f

commitHash = "unknown"
