math: use fabs on __ieee754_lgamma_r

clang issues:

  ../sysdeps/ieee754/dbl-64/e_lgamma_r.c:234:29: error: absolute value function 'fabsf'
  given an argument of type 'double' but has parameter of type 'float' which may cause \
  truncation of value [-Werror,-Wabsolute-value]

It should not matter because the value is 0.0, but using fabs is
simpler than adding a warning suppresion.
