We try to write sstate with group-write permissions so that sstate-cache
can be shared between multiple users. However the siginfo files are
created in various tasks which may set their own umask (such as
do_populate_sysroot, 0022). This results in no group write permission
on the intermediate directories, which is fatal when sharing a cache.
Fix this by wrapping the siginfo mkdir in a umask change to 0002.
