linux-user: remove useless variable
filename is only used to open the file if AT_EXECFD is not provided.
But exec_path already contains the path of the file to open.
Remove filename as it is only used in main.c whereas exec_path is
also used in syscall.c.
Fixes: d088d664f201 ("linux-user: identify running binary in /proc/self/exe")
