(jm_LIST_MOUNTED_FILESYSTEMS)
Check for these headers: sys/param.h sys/ucred.h sys/mount.h
sys/fs_types.h, and make the link-test for getfsstat guard #include
directives with appropriate #if HAVE_*_H tests so that we can
detect getfsstat on Apple Darwin1.3.7 systems.

Also fix harmless typo in cache variable name: s/getsstat/getfsstat/.
