btrfs-progs: restore backtrace functionality on glibc

Originally broke in commit c2691f807ddd2c6b261c5707f6838a45d9275390

__glibc__ should have been __GLIBC__

We also include features.h ; although most includes (at least stdlib.h)
typically already include it -- at least on glibc, where it matters.
