Add --clearenv option
This allows environment variables to be set when running bwrap itself
(perhaps a custom LD_LIBRARY_PATH), but cleared for the command that
runs in the container, without having to enumerate all the variables.
Because PWD is set later, as a side-effect of changing directory, this
actually clears everything except PWD.
A portable program would check for clearenv() (and if not found, fall
back to using environ = NULL), but bubblewrap is Linux-specific, and
Linux C libraries (at least glibc and musl) do have clearenv().
