vpath usage - simplify to bare minimum to make gustavo happy

since these are only local path resolves, the do and wait are
technically not needed. also remove any other tmp strings
and use the vpath string resolving feature to avoid
printfs/strjoins/cats etc. etc. as well.

also remember to remove old name string from evas shm code - it worked
for me. i guess i was lucky and it happened to be NULL thus free was
fine.
