Subject: git-gui: Make git-gui lib dir configurable at runime

Introduce the GIT_GUI_LIB_DIR environment variable, to tell git-gui
where to look for TCL libs.  This allows a git-gui which has been
built with a prefix of /foo to be run out of directory /bar.  This is
the equivalent of GIT_EXEC_PATH or GITPERLLIB but for git-gui's TCL
libraries.
