Local secure_getenv() at the moment uses getauxval(AT_SECURE), but it's
not always present in libc and secure_getenv() instead could be.

Check if secure_getenv() is available from libc and use it, otherwise
workaround it using issetugid().

Giulio Benetti (2):
  meson: check if secure_getenv() is present
  libcamera: utils: call secure_getenv() if it exists or workaround with
    issetugid()
