relocatable-prog-wrapper: Fix syntax error on Linux

[Bruno Haible via Gnulib discussion list]

Packages that include the 'relocatable-prog' module show a syntax error
when configured with --enable-relocatable on Linux:

progreloc.c: In function ‘find_executable’:
progreloc.c:264:29: error: ‘buf’ undeclared (first use in this function)
  264 |       executable_fd = open (buf, O_EXEC | O_CLOEXEC, 0);
      |                             ^~~

This patch fixes it.
