[Buildroot] [PATCH v2] sylpheed: Fix includedir

[Valentine Barshak <gvaxon@gmail.com>]

The sylpheed headers are installed to the target directory,
creating full staging directory path in the target rootfs,
which is wrong.
This happens because the headers are installed to
$(DESTDIR)$(includedir), while DESTDIR is $(TARGET_DIR)
and includedir is set to $(STAGING_DIR)/usr/include in the
SYLPHEED_CONF_OPT.

The includedir was set to staging include because sylpheed
incorrectly adds includedir to its include path, and does
not build with the default includedir set to /usr/include
in the target filesystem.

This removes includedir setting and also removes it from
include paths in Makefiles. The same approach is used
in the OE.
