libhugetlbfs: use next branch instead of master

Master hasn't been updated since 2 years (December 2015). Next branch
received some fixes/updates and is only 23 commits ahead of master.

Switch from master to next branch:
* update PV to include SRCPV and "+next" string
* update SRCREV
* update SRC_URI to use next branch
* drop Force-text-segment-alignment-to-0x08000000-for-i386-.patch which is
  a backported patch from next branch

-Subject: [PATCH] Force text segment alignment to 0x08000000 for i386 with gold
- linker
-
-Upstream-Status: Backport
-
-When build libhugetlbfs tests with gold linker for i386, the below error occurs:

-
-But, it works well with GNU linker. --hugetlbfs-align flag passes
-"-zcommon-page-size=$SLICE_SIZE -zmax-page-size=$SLICE_SIZE", that are supported by gold linker too.
-But, it looks gold linker deal with them in a different way from gnu linker for i586.
-
-The readelf shows the below result with GNU linker:
-
-Elf file type is EXEC (Executable file)
-Entry point 0x8048fbd
-There are 8 program headers, starting at offset 52

-The fix just have impact on hugelink_rw test case, which needs --hugetlbfs-align flag.
