Add USE conflict unit test for bug 615824

Test bug 615824, where an automask USE change results in
a conflict which is not reported. In order to install L,
foo must be disabled for both K and M, but autounmask
disables foo for K and leaves it enabled for M:

[ebuild  N     ] sci-libs/K-1  USE="-foo"
[ebuild  N     ] sci-libs/L-1
[ebuild  N     ] sci-libs/M-1  USE="foo"

The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by sci-libs/L-1::test_repo
# required by sci-libs/L (argument)
>=sci-libs/K-1 -foo
