pw_env_setup: Remove unnecessary unset calls

The _pw_cleanup variable is never set in the first place (the deleted
line was the only place it appeared in Pigweed code). The
_pw_alias_check can be made local.

Removing these spurious unsets will avoid warnings being printed when
running bootstrap from zsh.

Tested by running `source bootstrap.sh` from zsh. Without this change,
it prints the warnings; with this change, it does not.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.
