JDK-6191542 - getTotalSwapSpaceSize() returns wrong swap file size on linux-amd64.
Description
Swap sapce info reported by MM on some linux machine may not be correct.
The sysinfo() returns memory size in mem_units bytes. So we need to 
multiply the free swap and total swap and other memory information
with mem_units.

EVALUATION The sysinfo structure was modified since Linux 2.3.23, 2.3.48. The sizes are given as multiples of mem_unit bytes (no longer in bytes). 6191542 modified com.sun.management.UnixOperatingSystem to get swap space info from sysinfo instead of /proc but assumes the sizes are in bytes which is incorrect when running on Linux 2.3.48 or later releases. Fix this in Mustang. ###@###.### 2005-04-11 16:53:00 GMT
