This is only required when doing cargo build so have moved it to exec_cargo_for_wasm_target.

This min version check can be replaced by adding rust_version to the ink crate, might be a more suitable location for it?

@HCastano reported the following error when using
cargo +nighlty testfor E2E tests using the newcontract-buildlibrary. First of all the error is misleading and is an occurrence of #746.The issue is that the
+nightlygets inherited and theassert_channelcheck fails. This PR removes this check entirely and allows the underlyingcargo buildcommand to inherit whatever toolchain the user needs. It still does addRUSTC_BOOTSTRAPin case we are building withstable.This should now be more in line with
cargophilosophy and give more flexibility to contract authors with their toolchain management.See also #698 where stable toolchain was first introduced.
