Because search path fields are not delayed, this is susceptible to
introduce circular dependencies between modules (see: "info (guix)
Cyclic Modules Dependencies").  It' be better to either repeat it, or
define some %libxslt-search-paths variable among the (guix search-paths)
module to be reused elsewhere.
