pkg/email: move patch parsing from pkg/kernel

ParsePatch is used by appengine app.
Appengine apps can't depend on syscall/unsafe,
but pkg/kernel currently does.
Move patch parsing to pkg/email which does not
depend on syscall/unsafe.

-To: Foo Bar <foo@bar.com>
-Subject: [PATCH v2] timerfd: Protect the might cancel mechanism proper
-MIME-Version: 1.0
-Content-Type: text/plain; charset=US-ASCII
-
-The handling of the might_cancel queueing is not properly protected, so
-parallel operations on the file descriptor can race with each other and
-lead to list corruptions or use after free.
-
-Protect the context for these operations with a seperate lock.
