blame.c: fix garbled error messagelf/blame-commit-label

The helper functions prepare_final() and prepare_initial() return a
pointer to a string that is a member of an object in the
revs->pending array.

Before 1da1e07c (clean up name allocation in prepare_revision_walk,
2014-10-15), these strings used to be non-volatile; they were
instead leaked more or less deliberately.  But these days, these
strings are cleared before running prepare_revision_walk() which
potentially transforms the pointer target into a bogus string.

Fix this by maintaining a copy of the original string.
