FreeSWITCH: Fix dependency on LZMA issue and sync to FS latest git HEAD

1. The FS libs/tiff package can make use of liblzma if avaialable. This
	fix reverts commit bff1f87ad70cd80456a9b6c77f1120141a7aea61. It
	checks the CONFIG_PACKAGE_liblzma variable to determine liblzma
	and will either pass --enable-lzma or --disable-lzma switch to
	configure. For mod-spandsp, +liblzma:liblzma automatically sets
	the liblzma dependency flag.
2. Synched to FS git HEAD d35db852a8bcc4fb10e7a8486046aabd45a7f9b2.
