Commit 2296f194dfde4c0a54f249d3fdb8c8ca21dc611b reduced the number
of syscalls performed during user emulation startup, but failed to
consider the use of symbolic links in creating directory structures.

The current init_paths code will attempt to opendir() every single file it
finds. This can obviously generated a huge number of syscalls with even a
moderately small sysroot that will fail. Since the readdir() call provides
the file type in the struct itself, use it. On my system, this prevents
over 1000 syscalls from being made at every invocation of a target binary,
and I only have a C library installed.
