Binbin Wu b13513e764 selftests/x86/lam: Zero out buffer for readlink() ...

[ Upstream commit 2906063341 ]

Zero out the buffer for readlink() since readlink() does not append a
terminating null byte to the buffer.  Also change the buffer length
passed to readlink() to 'PATH_MAX - 1' to ensure the resulting string
is always null terminated.
