Avoid use of large stack buffers in mbedtls_x509_write_crt_pem()

This commit rewrites mbedtls_x509write_crt_pem() to not use
a statically size stack buffer to temporarily store the DER
encoded form of the certificate to be written.

This is not necessary because the DER-to-PEM conversion
accepts overlapping input and output buffers.
