markers: fix duplicate modpost entry
When a kernel was rebuilt, the previous Module.markers was not cleared.
It caused markers with different format strings to appear as duplicates
when a markers was changed. This problem is present since
scripts/mod/modpost.c started to generate Module.markers, commit
b2e3e658b344c6bcfb8fb694100ab2f2b5b2edb0
It therefore applies to 2.6.25, 2.6.26 and linux-next.
I merely merged the patches from Roland, Wenji and Takashi here.
Credits to

for providing the individual fixes.
- Changelog :
- Integrated Takashi's Makefile modification to clear Module.markers upon
make clean.
