FreeSWITCH: Fix dependency on LZMA issue, add some minor adjustments to
	modules depend on PACKAGE_alsa-lib, and sync to FS latest git HEAD

1. Previous commit (c038dad49a9d75e5de87663b017abdc76802fb41) didn't
	seem to fix this issue. Hopefully, this fix that partially
	reverts previous commit will.
2. This commit also includes some minor adjusments to modules depend on
	PACKAGE_alsa-lib.
3. Synched to FS git HEAD dbfde499a42b4f72eaf5578da2ebc741b85dedb3.
