app-mobilephone/smssend, dev-libs/skyutils: fix SSLv3 support.

In commits 790eacc and ac28332, I added an "sslv3" USE flag to
dev-libs/skyutils and revisioned app-mobilephone/smssend to depend on
it. This fix was insufficient; any other programs linking to
libskyutils would suffer the same problem, as Michał Górny pointed
out.

Two new revisions of the affected packages remove the "sslv3" option
for dev-libs/skyutils, and make it depend on openssl[sslv3] when the
user asks for SSL support. Note: this required the removal of LibreSSL
support on skyutils. The new revision of app-mobilephone/smssend now
depends on the fixed revision of skyutils.

An additional fix was made, and now smssend depends on
skyutils[ssl]. Without SSL support in libskyutils, many SMS providers
simply don't work.
