[gentoo-dev] [PATCH] epatch.eclass: drop 'estach.eclass' usage

[Sergei Trofimovich]

Avoid use of eshopts_push / eshopts_pop functions
as they don't preserve expand_aliases shell option
and get detected by QA warning as:
  * QA Notice: Global shell options changed and were
  not restored while calling 'src_prepare'

Ssee bug #662586 for details.

Tested as:
    $ EPATCH_USER_EXCLUDE="*" ebuild gcc-8.2.0.ebuild clean prepare
