Store the private key with read and write permission for the user only
and not with read permissions for everyone. This converts the
write_file() function from fopen() to open() because open allows to
specify the permission mask of the newly created file. It also adds and
fixes some existing error handling.
OpenSSL does this in the same way already.
With this change it looks like this:
root@OpenWrt:/# ls -al /etc/uhttpd.*
-rw-r--r-- 1 root root 749 Nov 6 23:14 /etc/uhttpd.crt
-rw------- 1 root root 121 Nov 6 23:14 /etc/uhttpd.key

(cherry picked from commit 6aad5ab099)
Chromium based web-browsers (version >58) checks x509v3 extended attributes.
If this check fails then chromium does not allow to click "Proceed to ...
(unsafe)" link. This patch add three x509v3 extended attributes to self-signed
certificate:
1. SAN (Subject Alternative Name) (DNS Name) = CN (common name)
2. Key Usage = Digital Signature, Non Repudiation, Key Encipherment
3. Extended Key Usage = TLS Web Server Authentication
SAN will be added only if CONFIG_WOLFSSL_ALT_NAMES=y

Certificate signature algorithm was being set after call to
`wc_MakeCert`, resulting in a mismatch between specified signature in
certificate and the actual signature type.

This package creates certificates and private keys, just like `px5g`
does. Hower it uses WolfSSL rather than MbedTLS.
