bash: fixed ptest run-builtins failed

1. redirect the stderr output of the command exec with -l option to
   /dev/null.
   Because when we run command exec with -l option in builtins.tests,
   it is a login shell, so it would read the file /etc/profile, that
   file executes the /usr/bin/resize which added by commit:
	 cc6360f4c4d97e0000f9d3545f381224ee99ce7d
   The /usr/bin/resize is produced by busybox that source code resize.c
   contains:
	fprintf(stderr, ESC"7" ESC"[r" ESC"[999;999H" ESC"[6n");
   In the end, it outputs an escape sequence to the stderr, so when we
   compare the test output file /tmp/xx with builtins.right, it failed.
   we need to redirect the stderr output to the /dev/null to solve the
   problem.

2. ensure the target system contains the locales "en_US.UTF-8".
   Because when run the run-builtins, it executes the source5.sub file
   that contain:
	LC_ALL=en_US.UTF-8
   such as add the following to the local.conf:
	IMAGE_LINGUAS_append = " en-us"
