package/libshout: add patches to fix static linking

This series includes two patches to fix static linking with libshout.

The first patch fixes two typos resulting in an uninterpretable library
propagation and is mainly needed for the follow-up patch.

The second patch makes sure that `@SHOUT_REQUIRES@` and therefore
`Requires.private` includes ssl as `Requires.private` defines a list of private
packages required by this package but not exposed to applications.

Note that autoreconf is enabled as the first patch touches configure.ac.

Fixes:

+Subject: [PATCH 2/2] Make sure @SHOUT_REQUIRES@ contains OpenSSL
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Static linking userspace programs such as mpd against libshout
+currently doesn't work out of the box, because libshout is linked
+against libssl, but this isn't expressed in libshouts pkg-config
+file:
+
+```
+/usr/lib/libshout.a(tls.o): In function `tls_check_cert':
+tls.c:(.text+0x10): undefined reference to `SSL_get_peer_certificate'
+tls.c:(.text+0x24): undefined reference to `SSL_get_verify_result'
+tls.c:(.text+0x4c): undefined reference to `X509_get_subject_name'
+tls.c:(.text+0x60): undefined reference to `X509_NAME_get_text_by_NID'
+tls.c:(.text+0x118): undefined reference to `X509_NAME_get_entry'
+tls.c:(.text+0x11c): undefined reference to `X509_NAME_ENTRY_get_data'
+tls.c:(.text+0x120): undefined reference to `ASN1_STRING_length'
+tls.c:(.text+0x148): undefined reference to `X509_free'
+tls.c:(.text+0x178): undefined reference to `X509_NAME_get_index_by_NID'
+```
+
+Since OpenSSL installs its own .pc files, make sure that @SHOUT_REQUIRES@
+contains `ssl`.
