init: Check for symlinks with lstat() not open()

Using open() with an O_NOFOLLOW flag will result in a file falsely
being determined to be a symlink if the open fails for another
reason.

For example, a character device that isn't ready due to the
underlying hardware not being initialized yet will fail to open()

An example of this are any CG2900 device files prior to
execution of ste-cg29xx_ctrl

This uses lstat() instead of open() with O_NOFOLLOW to check
whether a file is a symlink or not.

New fix for 4.3 gralloc
Improve exec command processing

- Make exec print out an error if execve() failed for some reason
- Pass init's environment, created by the export keywords, to the exec'd
  command, which is helpful when running shell scripts (for PATH) and/or
  am (for BOOTCLASSPATH) from an exec statement.
