[PATCH v2] column: fix compilation when libc lacks wide-character support

[Carlos Santos <casantos@datacom.ind.br>]

Commit 4762ae9d removed mtsafe_strtok() but left behind calls to wcstok
and wcspbrk. This leads to build failures when libc does not have the
wide-character functions, like some uClibc builds.

Solve the problem by using strtok_r and strpbrk when HAVE_WIDECHAR is
not defined.
