e2fsprogs: Backport fixes for building with musl

Both of these fixes have been applied upstream and improve general code
correctness.  They are needed when building with TCLIBC=musl but shouldn't cause
any harm with other libc implementations.

+Subject: [PATCH] Fix musl build failures
+
+In lib/ext2fs/unix_io.c, __u64 should be used instead of __uint64_t. This type
+is guaranteed by the e2fsprogs build system.
+(795c02def3681a99cc792a5ebc162d06f8a1eeb7)
+
+In misc/create_inode.c, <limits.h> is needed for the definition of PATH_MAX.
+(bbccc6f3c6a106721fb6f1ef4df6bc32c7986235)
+
+Both of these fixes have been made upstream with the git commit IDs given but
+those are larger commits containing other changes not needed here.
