test: recover binary_installer full-compat port; implement posix_getpwuid

The stashed binary_installer port was blocked on posix_getpwuid (reached via
Platform::is_virtual_box_guest); implement it via getpwuid(3) extern "C". The
4 install-and-exec tests now pass with the stream I/O and Process cwd fixes.
