Subject: Customize installation directory using INSTALL_DIR environment
 variable

Previously, minirake installed several commands (e.g., mrbc) in
repository locally under bin directory.  But there was no knob for
users to change this directory.  It effectively made `make distcheck`
fail if mruby was embedded into project managed by autotools.

This change adds a way for the user to change installation directory
by setting INSTALL_DIR environment variable.
