xbps-create: if a symlink points to an unexistent file store symlink target as is.

Browse Source 
Seen in recent builds when building the systemd binpkg:

[chroot] => Building systemd-194_1.x86_64.xbps...
xbps-create.real: main.c:219: ftw_cb: Assertion `p' failed.

Which was asserting in a symlink that was pointing to a file provided by the udev
pkg, therefore realpath(3) failed.
