Subject: [PATCH] sane_backend: add missing config.h

We should include config.h from sanei_backend.h in order to use the
correct if/else HAVE_FOO.

For some reason with Glibc or uClibc there is no problem but with musl
we have the following weird issue:

In file included from epsonds.h:41:0,
                 from epsonds-jpeg.c:18:
../include/sane/sanei_backend.h:99:33: error: expected ';', identifier or '(' before 'int'
 # define sigset_t               int
                                 ^
../include/sane/sanei_backend.h:99:33: warning: useless type name in empty declaration

That's because HAVE_SIGPROCMASK is not defined although it's correctly
detected by the configure script.

$ grep config.log
config.log:#define HAVE_SIGPROCMASK 1

So, include config.h to avoid to redefine sigset_t.

Fixes:
