Remove PQunescapeBytea hack from pgsql2shp which is no longer needed, as it was only...

- *              PQunescapeBytea - converts the null terminated string representation
- *              of a bytea, strtext, into binary, filling a buffer. It returns a
- *              pointer to the buffer (or NULL on error), and the size of the
- *              buffer in retbuflen. The pointer may subsequently be used as an
- *              argument to the function free(3). It is the reverse of PQescapeBytea.
- *
- *              The following transformations are made:
- *              \\       == ASCII 92 == \
- *              \ooo == a byte whose value = ooo (ooo is an octal number)
- *              \x       == x (x is any character not matched by the above transformations)
