[Vala] [PATCH] Use valac instead of vala as a compiler

[Anatol Pomozov <anatol pomozov gmail com>]

If we leave vala it produces following error:

$ ./autogen.sh --prefix=/opt/vala
No source file specified.
**Error**: You must have valac >= 0.7.0 installed
  to build vala. Download the appropriate package
  from your distribution or get the source tarball at
  http://download.gnome.org/sources/vala/

The underlying problem is that 'vala --version' does not produce
version string.

$ /opt/vala/bin/vala --version
No source file specified.
$ /opt/vala/bin/valac --version
Vala 0.10.0
