[avb] Add gn option to opt out using posix sysdeps

The existing implementation in avb_sysdeps_posix.cc does things like
"fprintf(stderr,..." which is not supported in physboot efi toolchain.
The CL adds a gn option to opt out of using it. This allows applications
built by non-supporting toolchains to implement their own sysdeps.
