core: Unbreak build on FreeBSD (#8762)
* CrashReporter: restore explicit environ(7) after 8bbeee1173

BSD systems don't declare environ(7) in any header like POSIX suggests.

src/signal-safe.cpp:12:23: error: use of undeclared identifier 'environ'
   12 |     for (char** var = environ; *var != nullptr; var++) {
      |                       ^

* fix
