func_strings.c: Prevent SEGV in HASH single-argument mode.

When in single-argument mode (very rarely used), a malformation of a column
name (also very rare) could cause a NULL to be returned when retrieving the
channel variable for that column.  Passing that to strncat causes a SEGV.  We
now check for the NULL and print a warning message.

Resolves: #1101
