bfstd: New sysoption() macro to check for POSIX option runtime support
POSIX allows optional features to be supported at compile time but not necessarily at run time by defining _POSIX_OPTION to 0 and requiring users to check sysconf(_SC_OPTION) > 0. The new sysoption() macro simplifies the check. sighook() and bfs_spawn() now check for conditional runtime support for the relevant POSIX options.
