/system/bin/sh exists only on Android. When Bionic is built for the
host, use the standard /bin/sh.

We regressed on this recently: code under the upstream-* directories has
_PATH_BSHELL defined as a call to __bionic_get_shell_path(). In our own
code, we may as well just call it directly.

For treble enabled devices, still return the appropriate shell depending
on whether the process is a vendor process or a system one.
Test: Manual testing: on a bullhead device, ran test programs from
/vendor/bin which used popen() and system(). The calls succeeded.

(cherry picked from commit 1e52871773)
Library calls like system() and popen() invoke the shell executable
pointed to by '_PATH_BSHELL' in order to run the command passed into the
function. The _PATH_BSHELL points to /system/bin/sh by default and thus
breaks any vendor process trying to use system() / popen(), as they are
denied access to system shell by selinux.
This CL make necessary changes, so the implmentations of system() and popen()
can use the appropriate shell (e.g. /vendor/bin/sh for processes running
out of /vendor partition). Also, changes the implementation of system()
and popen().

Test: Manual, Using a test program running from /system/bin and
/vendor/bin to ensure correct shell is being used.
