Fix two small problems. (Sorry they are merged in one commit since I'm lazy)

1: Fix makefile: no redundant sudo in the command line. That makes no difference for everyone since the sudo is redundant, and fixes the bug for myself since I do not use sudo.

2. Fix mbpfan.c: no more sudden silence if you start this daemon when your system is already very hot. This is due to a 7-second delay between the starting of this daemon and the first change fan speed command. I feel this too dangerous since I was running this with CPU temperature at 92 degree and had to wait for that 7 seconds praying that it won't hit 100 during this....
