mktemp: warning fix for x86 and l-preview

mktemp is almost not used in busybox, so rename
the function in the mktemp applet to prevent bionic
warning on include.

Bionic changes for tty related applets

Tested (but applets not included/enabled)
getty, login, su, passwd, mkpasswd, cryptpw

Sample /etc/passwd required before 'passwd' :
root:x:0:0:root:/:/system/xbin/bash

busybox su allow to change current user, if you are root
Example: "busybox su shell -c /system/xbin/bash"

busybox login allow also to do that :
Example: "busybox login shell"

getpwnam() returns now an empty string in passwd member
instead of null, busybox often check directly pw->pw_passwd[0]

Update also selinux related stubs after tests on x86 4.4.2,
l-preview and aosp/master

If you want to include these applets, here is the required
source list to add in busybox-full.sources :

 libbb/correct_password.c libbb/pw_encrypt.c libbb/update_passwd.c
 loginutils/getty.c loginutils/login.c loginutils/su.c
 loginutils/passwd.c loginutils/chpasswd.c loginutils/cryptpw.c

And the config flags to add :

 CONFIG_GETTY=y
 CONFIG_LOGIN=y
 CONFIG_FEATURE_NOLOGIN=y
 CONFIG_PASSWD=y
 CONFIG_CRYPTPW=y
 CONFIG_CHPASSWD=y
 CONFIG_SU=y
 CONFIG_FEATURE_SU_CHECKS_SHELLS=y
