[Handle sysconf(3) return value -1 when checking _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX.
bjorn@bringert.net**20070416214837
 sysconf(3) returns -1 on failure, but this was not handled when checking _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX in System.Posix.User. This made getUserEntryForID, getUserEntryForName, getGroupEntryForID and getGroupEntryForName fail on OS X 10.4.9 on i386. Just checking that unistd.h defines _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX as was done before does not guarantee that sysconf(3) will succeed.
 
 sysconf(3) failure is now handled by using the same default values as were already used when sysconf(3) is not available, or the parameter names are not defined.

[Added tests/user001.hs which tests all the get* functions in System.Posix.User.
bjorn@bringert.net**20070416220012
 I added this since I noticed that getUserEntryForID, getUserEntryForName,
 getGroupEntryForID and getGroupEntryForName failed on OS X 10.4.9 on i386.
