fast-import.c: Fix big-file-threshold parsing bug

Manual merge made at 844ad3d (Merge branch 'sp/maint-fast-import-large-blob'
into sp/fast-import-large-blob, 2010-02-01) did not correctly reflect the change
of unit in which this variable's value is counted from its previous version.

Now it counts in bytes, not in megabytes.
