bitbake: siggen: use correct umask when writing siginfo

Browse Source 
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.

(Bitbake rev: 75d9ef04a908e366633b255d23ab3275f6860d3a)
