[LTP] [PATCH 1/1] tst_test.sh: Remove possible double/trailing slashes from TMPDIR

[Petr Vorel]

NFS tests have problem when TMPDIR path contains double slashes,
because they grep exportfs output which is normalized.

Problem is either trailing slash:

$ TMPDIR=/var/tmp/ nfs01.sh -t tcp
...
nfs01 1 TINFO: Mounting NFS: mount -v -t nfs -o proto=tcp,vers=3 10.0.0.2:/var/tmp//LTP_nfs01.sIqm4LLS4u/3/tcp /var/tmp//LTP_nfs01.sIqm4LLS4u/3/0
nfs01 1 TINFO: starting 'nfs01_open_files 1000'
nfs01 1 TPASS: test finished successfully
nfs01 2 TINFO: Cleaning up testcase
nfs01 2 TINFO: remote_dir: '/var/tmp//LTP_nfs01.sIqm4LLS4u/3/tcp'
exportfs: Could not find '*:/var/tmp//LTP_nfs01.sIqm4LLS4u/3/tcp' to unexport.
rm: cannot remove '/var/tmp//LTP_nfs01.sIqm4LLS4u/3/0': Device or resource busy
rm: cannot remove '/var/tmp//LTP_nfs01.sIqm4LLS4u/3/0': Is a directory

or double (or more) slashes (anywhere in $TMPDIR):

$ TMPDIR=/var//tmp nfs01.sh -t tcp
nfs01 1 TINFO: Mounting NFS: mount -v -t nfs -o proto=tcp,vers=3 10.0.0.2:/var//tmp/LTP_nfs01.qNjSsopVbY/3/tcp /var//tmp/LTP_nfs01.qNjSsopVbY/3/0
nfs01 1 TINFO: starting 'nfs01_open_files 1000'
nfs01 1 TPASS: test finished successfully
nfs01 2 TINFO: Cleaning up testcase
nfs01 2 TINFO: remote_dir: '/var//tmp/LTP_nfs01.qNjSsopVbY/3/tcp'
exportfs: Could not find '*:/var//tmp/LTP_nfs01.qNjSsopVbY/3/tcp' to unexport.
rm: cannot remove '/var//tmp/LTP_nfs01.qNjSsopVbY/3/0': Device or resource busy
rm: cannot remove '/var//tmp/LTP_nfs01.qNjSsopVbY/3/0': Is a directory

While this could be handled in nfs_lib.sh, it's better to save it for
all tests. It's easier to modify $TST_TMPDIR, because the problem
narrows down to double slash.
