[OE-core] perform_packagecopy can't handle bindir==base_bindir and errors out

[Koen Kooi]

Hi,

I'm currently trying to combine {base_}{lib,bin}dir and have set base_prefix to /usr and redefined some other vars:

+# Try to move distro stuff under /usr
+# Keep /etc and friend in /
+base_prefix = "/usr"
+nonarch_base_libdir = "/lib"
+sysconfdir = "/etc"
+servicedir = "/srv"
+sharedstatedir = "/com"
+localstatedir = "/var"

This hits a few problems (see tcpwrapper patch), but a bigger problem is with perform_packagecopy and kmod:

I can't figure out why packagecopy wants to go into '/usr/usr', the kmod recipe itself seems fine.
