Marc Hartmayer 5fec1c3a5c util: Fix deadlock across fork()
This commit fixes the deadlock introduced by commit
0980764dee687e8da86dc410c351759867163389. The call getgrouplist() of
the glibc library isn't safe to be called in between fork and
exec (see commit 75c125641ac73473ba4b0542524d67a184769c8e).
