Subject: [PATCH] tests: fix race in aclocal/autoheader calls

Put the sleep 1 after aclocal run, same as autoreconf does.  This
guarantees that 'aclocal.m4' will have smaller timestamp than
'config.h.in' and avoids re-running autoheader later on.

* tests/testsuite.at (LT_AT_ACLOCAL): Sleep sec after aclocal run.
