Subject: [PATCH] SCRIPTS: build-vtest: allow to set a TMPDIR and a DESTDIR

Implement a way to set a destination directory using DESTDIR, and a tmp
directory using TMPDIR.

By default:

- DESTDIR is ../vtest like it was done previously
- TMPDIR  is mktemp -d

Only the vtest binary is copied in DESTDIR.

Example:

	TMPDIR=/dev/shm/ DESTDIR=/home/user/.local/bin/ ./scripts/build-vtest.sh
