install: Fix failed to create symbolic link hwlatdetect file exists 

The following build error can occur if you have done a previous make install

if test -n "/usr/lib/python2.7/site-packages" ; then \
	install -D -m 755 src/hwlatdetect/hwlatdetect.py /usr/lib/python2.7/site-packages/hwlatdetect.py ; \
	ln -s /usr/lib/python2.7/site-packages/hwlatdetect.py "/usr/local/bin/hwlatdetect" ; \
fi
ln: failed to create symbolic link `/usr/local/bin/hwlatdetect': File exists
make: *** [install] Error 1

I initially wanted to fix the error by removing the symbolic link, with rm -rf
but Andrew Burgess pointed out that you can just use the
ln's -f (force) flag. I like that solution better.
