bug#60620: [PATCH] copy.c: replace set_acl() with chmod_or_fchmod()

[Ondrej Valousek]

This patch replaces set_acl() funclion call with chmod_or_fchmod()
Both functions works (AFAIK) the same way (at least in Linux) so should be 
possible.
Using chmod_or_fchmod would also help us to reduce dependency on libacl
(see the forthcoming patch to qcopy-acl.c from Gnulib).
