Fixing bug in line editing of the shell with CTRL-U.
This patch fixes a tiny bug in the command line editing of the RTEMS shell.
Typing CTRL-U in the shell should remove all characters left of the cursor.
After pressing CTRL-U, the current implementation does wrongly place the cursor
at the end of the line instead at its beginning.
To reproduce the bug, start the shell and type 'abc123' (no <RETURN>):
~/src/rtems $ qemu-system-arm -net none -nographic -M realview-pbx-a9 \
-m 256M -kernel build/arm/realview_pbx_a9_qemu/testsuites/libtests/dl10.exe

RTL (libdl) commands: dl, rtl
RTEMS Shell on /dev/foobar. Use 'help' to list commands.
SHLL / # abc123
Then move the cursor onto the '1' by hitting three times the <ARROW-LEFT> key.
Next type <CTRL>-U:
SHLL / # 123
Note that the cursor is at the end of the line (after '3') instead of correctly
at the beginning (on the '1'), now.
Continuing typing 'echo ' incorrectly results in the output:
SHLL / # 123echo 123
The patch changes this behavior so that the cursor in the second last step will
be on the '1' and typing 'echo ' will then correctly reflected as:
SHLL / # echo 123
Close #4096.
