package/wpa_supplicant: fix libwpa_client.so build

Build target libwpa_client.so is not built regardless of whether the
option CONFIG_BUILD_WPA_CLIENT_SO is set or not. Add patch that
fixes wpa_supplicant build regression.

+Subject: [PATCH] build: re-enable options for libwpa_client.so and wpa_passphrase
+
+Commit a41a29192e5d ("build: Pull common fragments into a build.rules
+file") introduced regression into wpa_supplicant build process. Build
+target libwpa_client.so is not built regardless of whether the option
+CONFIG_BUILD_WPA_CLIENT_SO is set or not. This happens because config
+option is used before it is imported from the configuration file.
+Moving its usage after including build.rules does not help: variable
+ALL is processed by build.rules and further changes are not applied.
+Similarly, option CONFIG_NO_WPA_PASSPHRASE also does not work as
+expected: wpa_passphrase is always built regardless of whether the
+option is set or not.
+
+This commit re-enables options adding both build targets to _all
+dependencies.
