/proc/uptime contains a floating-point number with '.' as decimal separator.
It thus needs to be parsed with 'c_strtod', not 'strtod' (which expects a ','
on French and German locales).

readutmp, boot-time: Fix parsing of /proc/uptime.
* lib/boot-time-aux.h (get_linux_uptime): Use c_strtod, not strtod.
* lib/readutmp.c: Include c-strtod.h.
* lib/boot-time.c: Likewise.
* modules/readutmp (Depends-on): Add c-strtod.
* modules/boot-time (Depends-on): Likewise.
