um: falloc.h needs to be directly included for older libc
[ Upstream commit 35f3401317a3b26aa01fde8facfd320f2628fdcc ] When building UML with glibc 2.17 installed, compilation of arch/um/os-Linux/file.c fails due to failure to find FALLOC_FL_PUNCH_HOLE and FALLOC_FL_KEEP_SIZE definitions. It appears that /usr/include/bits/fcntl-linux.h (indirectly included by /usr/include/fcntl.h) does not include falloc.h with an older glibc, whereas a more up-to-date version does. Adding the direct include to file.c resolves the issue and does not cause problems for more recent glibc.
