Makefile: Add new targets and update meson command syntax

- For the "install" target, use "--skip-subprojects" so that only
  nvme-cli (and not the subprojects) get installed.
- For the "purge" target, add "meson subprojects purge".
- Added "update-subprojects" target
- Added "test-strict" target. This is to limit testing to nvme-cli
  and not all the subprojects.
