[Bug 1783810] [NEW] [SRU] blocks boot on core18

[Michael Vogt]

Public bug reported:

The current version of libuuid is using getrandom() without the
GRND_NONBLOCK flag. This means that in early boot the boot is blocked
until the crng is initialized to "level=1" which on virtual machines may
take some time.

Upstream fixed this in https://github.com/karelzak/util-
linux/commit/a9cf659e0508c1f56813a7d74c64f67bbc962538 and we should just
backport the fix.

[Impact]
 * Makes systems that use libuuid in early boot hang

[Test Case]
 * boot a fresh core18 system with kernel 4.15

[Regression Potential]
 * little, change is very targeted

This is uploaded to the bionic-proposed queue now.
