primecount: update to 7.7.

#### Testing the changes
- I tested the changes in this PR: **briefly**

This is a very minor update to fix the following:
```
$ python -c 'from primecountpy.primecount import prime_pi ; print(prime_pi(-1))'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "primecountpy/primecount.pyx", line 25, in primecountpy.primecount.prime_pi
  File "primecountpy/primecount.pyx", line 47, in primecountpy.primecount.prime_pi
cysignals.signals.SignalError: Bus error
```

After the update
```
$ python -c 'from primecountpy.primecount import prime_pi ; print(prime_pi(-1))'
0
```

We can now sleep in the comfort that such an important calculation can be done in void linux with success.

As expected, other values of `π(x)` are still ok and quick:
```
$ python -c 'from primecountpy.primecount import prime_pi ; print(prime_pi(1_000_000_000_000))'
37607912018
$ python -c 'from primecountpy.primecount import prime_pi ; print(prime_pi(1_000_000_000_000_000))'
