mkfs.ubifs: don't leak copied command line arguments

For some command line flags, the argument string is copied. Simply
writing over the buffer leads to a resource leak if the same flag
is specified on the command line more than once.

This patch adds a free() call to the old buffer before overwriting
it with the new copy.
