mod_ladspa: Set setenv() overwrite flag to replace empty LADSPA_PATH variables.

Browse Source 
For complete putenv()-like behaviour.

Further investigation on why putenv() caused EFAULTs on execve() and
segfaults on reload:

putenv(3):

   "The string pointed to by string becomes part of the environment,
    so altering the string changes the environment."

setenv(3):

   "This function makes copies of the strings pointed to by name and value
    (by contrast with putenv(3))."
