Fix a bunch of small system/core bugs.

Missing frees in:
  adb/file_sync_client.c
  fastboot/fastboot.c
  libsparse/output_file.c

Missing closedirs in:
  adb/file_sync_service.c
  cpio/mkbootfs.c
  libcutils/dir_hash.c

Potential buffer overrun in:
  gpttool/gpttool.c

Incorrect NULL check in:
  libsparse/backed_block.c
