ui: 'load*' no longer fails on Guile 2.2.3 upon EACCES or similar. 

Previously, if ~/.cache was not write-accessible, 'guix' would exit with
code 1 without printing any message.  That was because the 'make-stack'
call would fail since the exception (a 'system-error) came from
'compile-file', which was called at a point where TAG wasn't installed
yet.  Secondly, to mimick auto-compilation behavior, we just swallow
'system-error raised by 'compile-file'.

Reported by Clément Lassieur.

* guix/ui.scm (load*): Move 'compile-file' call in the dynamic extent of
TAG.  Catch 'system-error around it and ignore it.
