[libdispatch-dev] Solaris portability - PATCH - getprogname shim support

[Joakim Johansson]

Falling back to retrieving program name for libdispatch debug file using getexecname() for Solaris.

Also made the fallback getprogname function return a ‘const’ string to the program name to avoid warnings.

Cheers,
 
Joakim
