convert: drop a duplicate implementation of `dateutil.makedate()`

I noticed this because the signature generated by pytype recently changed to be
less specific.  When the method was introduced back in 337d728e644f,
`util.makedate()` didn't take an optional timestamp arg.  But now it does, and
the methods are the same (except the `dateutil` version validates that the
timestamp isn't a negative value).  I left the old method in place in case
anyone has custom convert code that monkey patches it.

import cffi
import os

ffi = cffi.FFI()
with open(
    os.path.join(os.path.join(os.path.dirname(__file__), '..'), 'bdiff.c')
) as f:
    ffi.set_source(
        "mercurial.cffi._bdiff", f.read(), include_dirs=['mercurial']
    )
ffi.cdef(
    """
struct bdiff_line {
    int hash, n, e;
    ssize_t len;
    const char *l;
};

struct bdiff_hunk;
struct bdiff_hunk {
    int a1, a2, b1, b2;
    struct bdiff_hunk *next;
};

int bdiff_splitlines(const char *a, ssize_t len, struct bdiff_line **lr);
int bdiff_diff(struct bdiff_line *a, int an, struct bdiff_line *b, int bn,
    struct bdiff_hunk *base);
