Log: fix detect_pax behavior on linux where procfs is mounted with
hidepid>=1
PID1 (init) isn't observable on systems with procfs mounted with
hidepid=1,2 unless build runs under root (for example on Gentoo
where package manager compiles under user 'portage'). This can be
fixed by replacing /proc/1/status with /proc/self/status (which is
visible to the build script).
