[vte] build: Manually generate the C source from the vala source

[Christian Persch <chpe src gnome org>]

commit 4e2f53632637abba42b1ac558b738b63de18441e
Author: Christian Persch <chpe src gnome org>

    build: Manually generate the C source from the vala source
    
    Don't use the automake vala support, instead just generate
    the C sources manually. This fixes a build failure on
    non-srcdir builds.
