meson: remove multi-line statement with trailing '\'

Error on meson 0.47:
```
meson.build:885:47: ERROR:  Expecting colon got eol_cont.
crypt_header = conf.get('HAVE_CRYPT_H') == 1 ? \
                                               ^
```

This seems to have been fixed in meson 0.50 after a report from
https://github.com/mesonbuild/meson/issues/4720
