Explicitly cast tolower() return value to char before storing in a char

For ancient historical compatibility, the C standards define the
<ctype.h> functions as taking & returning ints, but limiting them
to the subset of values that fit in a char.

Silences clang warning:
xkill.c:244:12: warning: implicit conversion loses integer precision: 'int' to
      'char' [-Wconversion]
            *cp = _tolower (*cp);
                ~ ^~~~~~~~~~~~~~
