dateutils: FTBFS on hurd-i386 (for review)

[Svante Signell <svante.signell@gmail.com>]

Hi,

Currently dateutils fails to build from source due to PATH_MAX being
used, and that constant is not defined on GNU/Hurd. The attached patch
avoid using PATH_MAX by redefining the function mkfifofn() to allocate
the string buf there and free the allocated buffers expfn and actfn in
the calling function differ() when not needed any longer. All 610 tests
run in the testsuite pass and they are a requisite for the package to
build.

Thanks!
