Corinna Vinschen 98669a2476 Cygwin: exec: check execute bit prior to evaluating script
When the exec family of functions is called for a script-like
file, the av::setup function handles the exec[vl]p case as
well.  The execve case for files not starting with a she-bang
is handled first by returning ENOEXEC.  Only after that, the
file's executability is checked.

This leads to the problem that ENOEXEC is returned for non-executable
files as well.  A calling shell interprets this as a file it should try
to run as script.  This is not desired for non-executable files.

Fix this problem by checking the file for executability first.  Only
after that, follow the other potential code paths.
