Hi,

Whilst working on the "reproducible builds" effort [0], we noticed that
liberasurecode could not be built reproducibly.

What happens is that erasurecode_version.h headers are
non-determinstically installed in the target binary depending on the
system clock. This is due to debian/tmp/usr/include not being created
and the install-exec-hook ignores errors.

The attached patch ensures debian/tmp/usr/include exists and therefore
the headers will always be there. Once applied, liberasurecode can be
built reproducibly using our reproducible toolchain.
