Subject: [PATCH] tests: fix paths to input files

The current test wrapper works only when the inputs are specified using
relative paths.  If they're specified with absolute paths, the driver
fails to detect the inputs because it always prepends the input dir name
which itself is a relative path:
$ cd tests
$ ./testwrapper.sh -d . -i $PWD/reject.txt -t ./reject_ver.table
<fails to open inputs>

This normally doesn't show up because people run `./configure` or, for
out of tree builds, `../configure`.  But if you happen to run configure
with an absolute path, then automake tends to generate absolute paths
as well leading to test failures.

Fix all of this by dropping the implicit input directory prepending.
In practice, it doesn't even make sense:
- INPUT_NAME is often a list of files, not just a single one
- the input directory is used to find the testname tables which are
  usually generated, so it's impossible to use files from both source
  and build directories
- most of the time, the full/correct path is already specified
