shutils/chroot.sh: create symlink for /etc/localtime
https://github.com/void-linux/void-packages/pull/27803

Description:
Currently /etc/localtime is copied from the host to the chroot.
According to [1] /etc/localtime should be a symlink and some R checks
fail because it is not. Instead of copying, this commit resolves the
symlink, creates the required file below /usr/share/zoneinfo and then
symlinks it to /etc/localtime inside the chroot.
