Subject: [PATCH] Fix wrong fallback value in os_page_detect when sysconf fails

Returned LG_PAGE (log2 of page size, e.g. 12) instead of PAGE (actual
page size, e.g. 4096) when sysconf(_SC_PAGESIZE) failed. This would
cause os_page to be set to an absurdly small value, breaking all
page-aligned operations.
