tests: adjust shell syntax that breaks AIX /bin/sh

[Collin Funk]

On AIX, /bin/sh causes a testsuite failure with an output like this:

    Running 
/home/collinfunk/findutils-4.10.0.40-d4417/find/testsuite/find.gnu/execdir-multiple.exp
 ...
    FAIL: execdir-multiple.new-O0, ./runme[6]: syntax error at line 7 : 
`newline or ;' unexpected
    ./runme[6]: syntax error at line 7 : `newline or ;' unexpected
    ./runme[6]: syntax error at line 7 : `newline or ;' unexpected
    ./runme[6]: syntax error at line 7 : `newline or ;' unexpected

Here is a small test program to show the issue:

    $ cat test.sh 
    #!/bin/sh
    for arg;
    do
      echo "$arg"
    done
    $ ./test.sh a b c
    test.sh[3]: 0403-057 Syntax error at line 4 : `newline or ;' is not 
expected.

But, if we move the 'do' AIX /bin/sh no longer chokes:

    $ cat test.sh 
    #!/bin/sh
    for arg; do
      echo "$arg"
     done
    bash-5.2$ ./test.sh a b c
    a
    b
    c

Normally I don't think this is worth fixing. But since it only affects
one test case I have attached a patch that fixes it.

Subject: [PATCH] tests: adjust shell syntax that breaks AIX /bin/sh

* find/testsuite/find.gnu/execdir-multiple.exp: Move the 'do' of a for
loop to the same line so AIX doesn't fail.
