[PATCH] setlocalversion: make tag local to try_tag()

[Yuntao Wang]

The tag variable is only used by try_tag(), but is currently declared
local to scm_version() and modified by try_tag().

Make tag local to try_tag() instead and remove the unused declaration
from scm_version().

No functional changes.
