dev-libs/libutf8proc: fix regression on Prefix.

The cleanup of commit 5640fe7f introduced a regression on pkg-config.
The make "prefix" variable should start with ${EPREFIX}, so that
libutf8proc.pc have prefix=EPREFIX/usr.

Otherwise libutf8proc.pc will contain prefix=/usr and inject a
-I/usr/include into the cflags, because non-EPREFIX /usr/include is
not a system include directory on Gentoo Prefix.  This will result in
drawing in host headers and error out.
