Fix potential NULL pointer dereference

This patch addresses a potential NULL pointer dereference when we try to
duplicate a string. The input pointer can be NULL and that may lead to
crashes. We simply add a check for that case.

* exec.c (exec_file_locate_attach): Prevent NULL pointer dereference
when duplicating a string.
