systat: Introduced sysputpage() to display large page size with human readable format.

[ota_j.email.ne.jp]

Summary

Using UI units allows to fit larger numbers in columns.
Stop calling v_page_size - this is a value that doesn't change at runtime.
Renamed WINDOW *wnd to *wd to avoid conflict with global *wnd variable.
Use bit-shift to convert page size to byte.

Test Plan

systat -vm 10 to compare screen.
My output is attached below for comparison.
