gnu: Add relocatable static Guile 3.0 variant.

* gnu/packages/patches/guile-2.2-default-utf8.patch: New file, extracted from
commit 2acfe022a740f79b593348cc6362cc4ee8f33bb4.
* gnu/packages/patches/guile-3.0-linux-syscalls.patch,
gnu/packages/patches/guile-3.0-relocatable.patch: New files.
* gnu/local.mk (dist_patch_DATA): Adjust accordingly.  Move all Guile patches
together while at it.
* gnu/packages/make-bootstrap.scm (%guile-3.0-static-stripped): New public variable.

+This hack makes Guile default to UTF-8.  This avoids calls to
+`iconv_open'; `iconv_open' tries to open shared objects that aren't
+available during bootstrap, so using UTF-8 avoids that (and UTF-8 has
+built-in conversions in glibc, too.)
