utils: Reduce the number of calls to the "dirname" command
utils.bbclass contains create_cmdline_wrapper() function that
creates wrapper script with additional arguments for any passed
"$cmd" command, and uses several calls to "dirname".
Because "dirname" is an external command, in cases of lots of
calls to wrapped "$cmd", each call of "dirname" will incur
significant overhead.
There are three same calls to "dirname": one for saving it`s
output to "realdir" variable, and other two in "exec" command.
So last two "dirname" calls can be replaced with cached value
from "realdir" variable.
