[PATCH] test/test_linux.rb: use plain ASCII in tempfile name

[Antonio Terceiro <terceiro@softwarelivre.org>]

From: Antonio Terceiro <terceiro@debian.org>

On Debian, this fixes the build against ruby2.3, which otherwise fails
with errors like:

RegexpError: /.../n has a non escaped non ASCII character in non ASCII-8BIT script
