SELinux: Move execmod to the common perms 

execmod "could" show up on non regular files and non chr files.  The current
implementation would actually make these checks against non-existant bits
since the code assumes the execmod permission is same for all file types.
To make this line up for chr files we had to define execute_no_trans and
entrypoint permissions.  These permissions are unreachable and only existed
to to make FILE__EXECMOD and CHR_FILE__EXECMOD the same.  This patch drops
those needless perms as well.
