[Freeipa-devel] Fix removal of ipa-kdc-proxy.conf symlink

[Christian Heimes]

Hello,

the attached patch fixes the first bug, that was reported by Fraser
today. installutils.remove_file() uses os.path.exists() to check if the
file still exists, which in turn uses stat(2). I have modified the
function to use os.path.lexists() instead. It doesn't follow symlinks.

Because httpinstance first removes the target file
/etc/ipa/kdcproxy/ipa-kdc-proxy.conf before it tries to remove the
symlink /etc/httpd/conf.d/ipa-kdc-proxy.conf, the
installutils.remove_file() ignores the dangling symlink.
