[PATCH] t6026-merge-attr: don't fail if sleep exits early

[Andreas Schwab <schwab@suse.de>]

Commit 5babb5bdb3 ("t6026-merge-attr: clean up background process at end
of test case") added a kill command to clean up after the test, but this
can fail if the sleep command exits before the cleanup is executed.
Ignore the error from the kill command.

Signed-off-by: Andreas Schwab <schwab@suse.de>
---
The failure can be simulated by adding a sleep after the last command to
delay the cleanup.
