lib: don't override bigger HISTSIZE and SAVEHIST values (#8993)

Browse source 
oh-my-zsh Changes the HISTSIZE and SAVEHIST values to fixed sizes,
however if a bigger value is set in ~/.zshrc, it will override it,
potentially causing the user history to be deleted.

So, only set these values if no other is set and if it is lower than the
default ones.
