[Replicant] [vendor_replicant-release-scripts] [PATCH 6/6] Add support for building Replicant 11

[Denis 'GNUtoo' Carikli]

If we don't source envsetup.sh, we have the following when
calling 'make clobber' in Replicant 11:
    build/make/core/main.mk:2: Calling make directly is no longer supported.
    build/make/core/main.mk:3: Either use 'envsetup.sh; m' or 'build/soong/soong_ui.bash --make-mode'
    build/make/core/main.mk:4: *** done.  Stop.
and sourcing envsetup.sh should also work on Replicant 6.0.

As Replicant 11 doesn't have a script to build a toolchain,
we don't run ./vendor/replicant/build-toolchain with
Replicant 11.

As for using $_dir instead of $dir, on Replicant 11, $dir is
set to 'product' after sourcing build/envsetup.sh so we
can't use it.
