system/zsh: add patch for deprecated egrep usage. fixes #977.

Commit 5d9ffc28fc6a0d99338cac0b020e3eac486bccfc bumped grep from
3.7 to 3.10, and 3.8 introduced warnings for use of egrep/fgrep,
which were deprecated in 2.5.3 from 2007.

These warnings cause zsh test diffs to fail.

Patch the tests to avoid deprecated behavior.

See also: #976.
