[Bug-tar] [PATCH] tests: avoid filerem01 failure in massively parallel test

[Jim Meyering]

Running make check TESTSUITEFLAGS=-j9
on a 4-core system causes something (enough I/O contention?)
that makes test #61 always fail for me:

   61: file removed as we read it (ca. 22 seconds)     FAILED (filerem01.at:37)

Here's output from the log dir/file:

This patch solves it for me:
