[PATCH] erofs-utils: remove AC_FUNC_MALLOC check

[Yue Hu]

From: Yue Hu <huyue2 at yulong.com>

Below erros happened when building for ARM64, rpl_malloc is not
supplied in that case, remove AC_FUNC_MALLOC can fix the errors.

mkfs_file.c: In function 'erofs_compress_file':
mkfs_file.c:600:2: error: implicit declaration of function 'rpl_malloc' [-Werror=implicit-function-declaration]
  inode->i_inline_data = malloc(EROFS_BLKSIZE);
  ^
mkfs_file.c:600:23: error: assignment makes pointer from integer without a cast [-Werror]
  inode->i_inline_data = malloc(EROFS_BLKSIZE);
                       ^
mkfs_file.c: In function 'erofs_init_compress_context':
mkfs_file.c:874:17: error: assignment makes pointer from integer without a cast [-Werror]
  ctx->cc_srcbuf = malloc(erofs_cfg.c_compr_maxsz);
                 ^
mkfs_file.c:875:17: error: assignment makes pointer from integer without a cast [-Werror]
  ctx->cc_dstbuf = malloc(erofs_cfg.c_compr_maxsz * 2);
                 ^
cc1: all warnings being treated as errors
make[2]: *** [mkfs_erofs-mkfs_file.o] Error 1
