signal: use BUILD_BUG() instead of _NSIG_WORDS_is_unsupported_size()
Kill _NSIG_WORDS_is_unsupported_size(), use BUILD_BUG() instead. This
simplifies the code, avoids the nested-externs warnings, and this way we
do not defer the problem to linker.
Also, fix the indentation in _SIG_SET_BINOP() and _SIG_SET_OP().
Note: this patch assumes that the code like "if (0) BUILD_BUG();" is
valid. If not (say __compiletime_error() is not defined and thus
__compiletime_error_fallback() uses a negative array) we should fix
BUILD_BUG() and/or BUILD_BUG_ON_MSG(). This code should be fine by
definition, this is the documented purpose of BUILD_BUG().
