[PATCH] mkswap: use 64k pages in file-existing test

Some systems run with kernels using page sizes other than 4K. The
file-existing test used a file of 10 pages at 4K. This would fail on
kernels with higher page sizes (here 16K) like this:

   mkswap: error: swap area needs to be at least 160 KiB

Use 10 * 64K pages, hopefully allowing all kernels with 4K, 16K, 64K
pages to pass the tests.

Noticed on Debian loong64 kernel 7.0.9+deb14-loong64, and on 
sparc64 and alpha.
