Revert "Delete Apache license from the sqlite build script"

This reverts commit 4a2e6bb8.

Reason for revert: 
This revert appears to be unnecessary.  The presubmit that raised an issue with the license passed on retry.  Also, since every other file in the package contains the same license, this file should have a license, too.
