databases/sqlcipher: Fix consumers

Rename installed files from *sqlite3* back to *sqlcipher*.
Unbreak consumers:

• finance/kmymoney
• finance/skrooge
• net-im/gurk-rs
• net-im/qTox
• net-p2p/retroshare
• databases/py-sqlcipher3

While here improve port:

• Use USES=localbase instead of CFLAGS+=-I${LOCALBASE}/include and LDFLAGS+=-L${LOCALBASE}/lib.
• Split long lines.
• Fix warnings from portclippy.
• Sort CONFIGURE_ARGS and CPPFLAGS.
