[OE-core] Remove do_install_append() from zsh's recipe

[Cody Piersall]

Hello,

The recipe for building zsh includes the following function:

do_install_append () {
    rm -fr ${D}/usr/share
}

For me, this is not a useful function because zsh store lots of nice
functionality in the "/usr/share/zsh/5.0.5/functions" directory.  This
includes things like typing cd <TAB> and autocompleting only for
directories.  I propose that this function be removed from the recipe
(patch below).  If someone needs this functionality, it would be easy
to add to their bbappend file.

This patch removes this do_install_append:
