kernel.spec: Remove tools/build/Build

JIRA: https://issues.redhat.com/browse/RHEL-29796
Upstream Status: RHEL only

Since f9a8f52ce4707e4 ("tools build: Avoid circular .fixdep-in.o.cmd
issues"), upstream known as ea97402 ("tools build: Avoid circular
.fixdep-in.o.cmd issues"), the file tools/build/Build no longer exists.

Remove the line that tries to copy it.
