main/zsh: /etc/zsh/zprofile tries and fails to add $HOME/bin to PATH

/etc/zsh/zprofile tries to append $HOME/bin to PATH, but fails to do so. /etc/zsh/zprofile contains the following on lines 5 and 6:

PATH="$PATH:$HOME/bin"
export PATH

However, the very next thing /etc/zsh/zprofile does is source /etc/profile, which does this:

export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

This clobbers the changes made on lines 5 and 6.

I'd suggest either:

• deleting lines 5 and 6 from /etc/zsh/zprofile, or
• moving them to the end of the file after _src_etc_profile gets run.

(There's an argument to be made that PATH shouldn't be set in zprofile at all, but I'll save that for another day. 😇)

Steps to reproduce:

1. apk add zsh
2. zsh -l
3. echo $PATH
