[PATCH] btrfsck.c: #include <sys/stat.h> to avoid compile failures with glibc >= 2.12

[Francis Galiegue]

Avoid these warnings during compile:

----
btrfsck.c: In function =E2=80=98maybe_free_inode_rec=E2=80=99:
btrfsck.c:323: warning: implicit declaration of function =E2=80=98S_ISD=
IR=E2=80=99
btrfsck.c:328: warning: implicit declaration of function =E2=80=98S_ISR=
EG=E2=80=99
btrfsck.c:328: warning: implicit declaration of function =E2=80=98S_ISL=
NK=E2=80=99
----

leading to a link failure:

----
btrfsck.o: In function `maybe_free_inode_rec':
btrfsck.c:(.text+0x110e): undefined reference to `S_ISDIR'
btrfsck.c:(.text+0x113b): undefined reference to `S_ISREG'
