Add Libtap as a bundled library (does not change any behaviour without --enable-libtap)

Detects system library as pre-1.4.13 and does not install the built-in library anymore

Tested on:
  - Linux x86_64, with and without local libtap (System libtap installed)
	- Linux x86, with and without local libtap (System libtap NOT installed)
  - Solaris SPARC, with and without local libtap, with and without system libtap installed
