Define POSIX macro to have strdup

https://github.com/profanity-im/profanity/commit/98c38dc6d6d29333c63f80327774f094610d8602
sets C99 as standard.

strdup() is not part of C99.

For now set `-D_POSIX_C_SOURCE=200809L` macro to have strdup() in C99.
Using `gnu99` instead would be another option.

We should take more care to use glib functions whenever possible.
