Subject: [PATCH] Use local EPREFIX for uniformity.

The EPREFIX variable is not readonly in EAPI 0, 1, and 2, so we can
declare EPREFIX as a local variable. We must be careful not to let this
variable leak into the environment of ebuild/eclass functions that we
call, since bash propagates local variables to nested function calls.
