[src/lngamma.c] No longer declare B as initialized with GCC (see r5534),

as the "may be used uninitialized" warning no longer occurs with latest
GCC: trunk revision 203899 (Debian 20131021-1), for the future GCC 4.9.
The warning still occurs with GCC 4.8.2 (Debian 4.8.2-1):

$ gcc-4.8 -O2 -Wall -c gamma.c
In file included from gamma.c:27:0:
gamma.c: In function ‘mpfr_gamma’:
lngamma.c:468:17: warning: ‘B’ may be used uninitialized in this function [-Wmaybe-uninitialized]
               B = mpfr_bernoulli_internal (B, m); /* B[2m]*(2m+1)!, exact */
                 ^
lngamma.c:165:10: note: ‘B’ was declared here
   mpz_t *B;
          ^
Note: with GCC 4.8.2, at least -O is needed to reproduce the warning,
and -Wmaybe-uninitialized without -Wuninitialized (or -Wall) doesn't
trigger the warning.
