posix_spawn-internal: fix module description

[Bruno Haible]

The creation of a specific testdir fails:

$ ./gnulib-tool --create-testdir --dir=../testdir1 --single-configure 
posix_spawn posix_spawn_file_actions_addchdir
...
executing aclocal -I glm4
missing file gltests/spawni.c
configure.ac:594: error: expected source file, required through AC_LIBSOURCES, 
not found
configure.ac:31: gl_INIT is expanded from...
configure.ac:594: the top level
autom4te: /usr/bin/m4 failed with exit status: 1
aclocal: error: echo failed with exit status: 1

The reason is that the module 'posix_spawn' is contained in gllib/ and the
module 'posix_spawnp' is contained in gltests/ (as a tests dependency).
So gltests/spawni.c does not exist, but gllib/spawni.c exists.

This patch fixes it.
