LU-16353 config: enable_foo variables mustn't contains space

$enable_crypto is in some circumstances set to "embedded llcrypt"
which contains a space.
When the code from lustre-build.m4 then tests the value with:

   if test x$enablecrypto = xyes

we get a syntax error from ./configure

We could add quotes to this comment, but for consistency we would need
to add quotes to ever other test for an enable_foo variable.

It is simpler just to ensure we don't add spaces.  So change the space
to a hyphen.
