textproc/yamcha: Fix segfault bugs in pkemine + mktrie

The textproc/cabocha package has been failing on i386 DragonFly for
months.  This was caused by segaults in two utilities provided by yamcha:
pkemine and mktrie.

Google brought up some pastebin sniplets indicating others had run into
the same issue, confirming the fixes.  With the revised yamcha utilities,
textproc/cabocha builds nicely on DragonFly.

+2) There is a duplicate delete; "is" was previously freed already.
