[Libosinfo] [PATCH 14/14] install-script: Return glib-allocated string from ::apply_xslt()

[Christophe Fergeau]

Strings created by libxml2 should be freed with xmlFree while glib ones
should be freed with g_free, so it's cleaner to allocate the string
returned from ::apply_xslt() with the glib allocator as it's meant to be
g_free'ed later on.
