tor: package improvements

* remove "torify" script
  - "torify" script is just a wrapper around torsocks,
    but torsocks is not currently present in packages.
* tor-geoip: fix "install" recipe:
  - use $(INSTALL_DATA) instead of $(CP) as a proper way
    of installing files
* drop deprecated configure option:
    "--with-ssl-dir" is considered deprecated and obsolete,
    while "--with-openssl-dir" is already present.
* build in parallel
* build with -ffunction-sections, -fdata-sections,
  --gc-sections and -flto
* remove "--disable-largefile" in CONFIGURE_ARGS
* remove "-std=gnu99" in EXTRA_CFLAGS
* use $(FPIC) in EXTRA_CFLAGS
* remove trailing whitespace

Compile- and run-tested on ar71xx/generic,
TP-Link Archer C7 v2 (world-wide version).
