tests: fix glob pattern for dynamic timer alignment

The number of space characters varies depending on the number of digits of the
timer, making some tests fail on slow machines in an unintended way:

Differential Revision: https://phab.mercurial-scm.org/D12381

In this test, we want to test LFS bundle application on both LFS and non-LFS
repos.

To make it more interesting, the file revisions will contain hg filelog
metadata ('\1\n'). The bundle will have 1 file revision overlapping with the
destination repo.

#  rev      1          2         3
#  repo:    yes        yes       no
#  bundle:  no (base)  yes       yes (deltabase: 2 if possible)

It is interesting because rev 2 could have been stored as LFS in the repo, and
non-LFS in the bundle; or vice-versa.

Generate bundles

  $ for i in normal lfs; do
  >   NAME=src-$i
  >   hg init $TESTTMP/$NAME
  >   cd $TESTTMP/$NAME
  >   [ $i = lfs ] && enablelfs
  >   commitxy
  >   commitz
  >   hg bundle -q --base X -r Y+Z $TESTTMP/$NAME.bundle
  >   SRCNAMES="$SRCNAMES $NAME"
  > done

Prepare destination repos

  $ for i in normal lfs; do
  >   NAME=dst-$i
  >   hg init $TESTTMP/$NAME
  >   cd $TESTTMP/$NAME
  >   [ $i = lfs ] && enablelfs
  >   commitxy
  >   DSTNAMES="$DSTNAMES $NAME"
  > done

Apply bundles

  $ for i in $SRCNAMES; do
  >   for j in $DSTNAMES; do
  >     echo ---- Applying $i.bundle to $j ----
  >     cp -R $TESTTMP/$j $TESTTMP/tmp-$i-$j
  >     cd $TESTTMP/tmp-$i-$j
  >     if hg unbundle $TESTTMP/$i.bundle -q 2>/dev/null; then
  >       hg verify -q && echo OK
  >     else
  >       echo CRASHED
  >     fi
  >   done
  > done
