[Xcb] [PATCH 1/6] Initialize automake earlier (bugfix for #66413)

[Daniel Martin]

This fixes:
    https://bugs.freedesktop.org/show_bug.cgi?id=66413
    Bug 66413 - libxcb 1.9.1: Fails to build on Arch Linux: \
        /home/<user>/install-sh: No such file or directory

Without that patch the search path for `install-sh` will become $HOME
and the `install` target will fail, when DESTDIR doesn't exist in
advance. (occured with automake 1.14 and autoconf 2.69)
