The 'syslog' macro cannot be resolved in the pre-unwind-handler
context. Failed to resolve 'syslog' in this context resulted in the swallowing
of all installation errors.

Fixes 5c04b00cf463a543b8ffc9eb55991f6b4cc145dd.

* gnu/installer.scm (installer-program): Do not try to resolve 'syslog' macro
in the pre-unwind-handler.

Hello,

Since the commit 5c04b00c, error reporting in the installer is broken. Sadly
this means that every error happening in the 1.1.0 release will result in an
installer restart, without any error information reporting. 

Thanks,

Mathieu
