src/sigs.c: Define "_BSD_SOURCE" and "__BSD_VISIBLE"

Browse Source 
SIGWINCH isn't POSIX-compatible and causes a compile error on several
platforms, such as OpenBSD:

    sigs.c: In function 'generic_hdlr':
    sigs.c:63: error: 'SIGWINCH' undeclared (first use in this function)
    sigs.c:63: error: (Each undeclared identifier is reported only once
    sigs.c:63: error: for each function it appears in.)
    sigs.c: In function 'sigs_init':
    sigs.c:97: error: 'SIGWINCH' undeclared (first use in this function)
    *** Error code 1

Define "_BSD_SOURCE" explicitly in this compilation unit to enforce
definition of the "SIGWINCH" constant. Also, set "__BSD_VISIBLE" to 1
since FreeBSD doesn't honor "_BSD_SOURCE".
