btrfs-progs: build: autoconf 2.63 compatibility

Commit 2e1932e6a38 (btrfs-progs: build: simplify version tracking)
started m4_chomp to strip the newlines from the version file.  m4_chomp
was introduced in autoconf 2.64 but SLE11 ships with autoconf 2.63.
For purposes of just stripping the newline, m4_flatten is sufficient.
