[LTP] [PATCH V4 6/6] swapoff01: make use of make_swapfile

[Li Wang <liwang@redhat.com>]

This patch updates the swapoff01 test setup by replacing the previous
swapfile creation method with a single call to make_swapfile, which
now creates a contiguous swap file.

This change simplifies the setup and fix failure on TMPDIR on btrfs.

Note: it is a single fix but better applied with behind the libswap updates.
