scriptexec: preserve original shell/interpreter path 

For example,

When failing to execute the script which starts with the above line,
an error message does not contain information for /path/to/name.
Instead, it contains only name. In addition, if /path/to/dir/, an error
message contains empty string for a name of a failed script.
