gnu: ld-wrapper: Also unset GUILE_LOAD_PATH.

The following problem was discovered while attempting to configure Guix to use
a locally built Guile tree, via its meta/uninstalled-env script, which would
attempt to use the newer Guile source files and fail with:

  Pre-boot error; key: unbound-variable, args: (#f "Unbound variable:
  ~S" (error) #f)collect2: fatal error: ld terminated with signal 6 [Aborted]

With the following change, a Guix user may now configure their build to use a
locally built Guile with e.g.:

  ~/src/guile/meta/uninstalled-env ./configure --localstatedir=/var \
  --sysconfdir=/etc

* gnu/packages/ld-wrapper.in: Unset GUILE_LOAD_PATH.  Also unset
GUILE_SYSTEM_PATH, for symmetry.  Streamline exec call, using the now fixed
'-l' option.
(ld-wrapper): Fix args being a nested list, and strip its arg0.
