Remove unneeded functions from libcompat.

Erwin fired up a ports build a couple of weeks ago and it seems the
following functions are not used by any of the 20k ports we have, which
makes me believe they don't have any purpose. Just remove them.

-.Dd June 15, 1993
-.Dt CFTIME 3
-.Os
-.Sh NAME
-.Nm cftime ,
-.Nm ascftime
-.Nd convert date and time to string
-.Sh LIBRARY
-.Lb libcompat
-.Sh SYNOPSIS
-.In time.h
-.Ft int
-.Fn cftime "char *s" "char *format" "const time_t *clock"
-.Ft int
-.Fn ascftime "char *s" "const char *format" "const struct tm *tmptr"
-.Sh DESCRIPTION
-.Bf -symbolic
-The
-.Fn cftime
-and
-.Fn ascftime
-functions are made obsolete by
-.Xr strftime 3 .
-.Ef
-.Pp
-Use of the functions
-.Fn cftime
-and
-.Fn ascftime
-is strongly deprecated, since there is no way to check for a buffer
-overflow condition.
-Use
-.Xr strftime 3
-instead.
-.Pp
-The
-.Fn ascftime
-function is almost identical to
-.Xr strftime 3 ,
-with the only exception that there is no parameter to tell about the
-maximal buffer length, and the
-.Fa format
-parameter defaults to
-.Dq %C
-if a
-.Em NULL
-pointer is given.
-.Pp
-The
-.Fn cftime
-function does the same job, but it first invokes
-.Xr localtime 3
-in order to convert the given
-.Fa clock ,
-then also performs the conversions as requested by the
-.Fa format
-argument.
-.Sh RETURN VALUES
-The
-.Fn cftime
-and
-.Fn ascftime
-functions return the number of characters written to the output
-buffer
-.Fa s ,
-not counting the trailing null character.
-.Sh SEE ALSO
-.Xr localtime 3 ,
-.Xr strftime 3
