removes obsolete libs

I build a rpm package with a modified [spotify-client.spec](https://gist.github.com/pschyska/9159b2a7a6fccdc22f81#file-spotify-client-spec) taken from from lpf-spotify-client.
I got into dependency problems installing the resulting rpm, because libssl and libcrypto were included both in 1.0.0 and 0.9.8 versions.

Just removing the .so's from the repo fixed that for me, although I get
````
/usr/lib64/spotify-client/Data/SpotifyHelper: /usr/lib64/spotify-client/libssl.so.1.0.0: no version information available (required by /lib64/libQtNetwork.so.4)
/usr/lib64/spotify-client/Data/SpotifyHelper: /usr/lib64/spotify-client/libcrypto.so.1.0.0: no version information available (required by /lib64/libQtNetwork.so.4)
/usr/lib64/spotify-client/Data/SpotifyHelper: /usr/lib64/spotify-client/libcrypto.so.1.0.0: no version information available (required by /lib64/libQtNetwork.so.4)

````
on running spotify (Fedora 20). The app seems to work mostly fine though, so I don't know if this is a problem.
The radio is only displayed after I resize the app window once.

As a side-note: The /usr/bin/spotify script sets `LC_NUMERIC=en_US.utf8`, however on my machine the locale seems to be named `en_US.UTF-8` (note the different spelling of UTF-8). Does this matter?

Thx for your great work :smile:
