package/optee-client: bump to version 3.19.0

Bumps OP-TEE client package version to OP-TEE release 3.19.0.

This package introduces a mandatory dependency on util-linux and
pk-config packages that were made optional in commit [1], following
3.19.0 release tag. The dependency is related to new library teeacl
for access control list based login identification. This change picks
that commit and defines the dependency only when TEEACL library is
to be embedded. The patch will be removed once we dump to the next
OP-TEE release tag, as state by new BR2 boolean config switch
BR2_PACKAGE_OPTEE_CLIENT_TEEACL.

[yann.morin.1998@free.fr:
  - actually backport upstream commit
  - don't default y for BR2_PACKAGE_OPTEE_CLIENT_TEEACL
  - select util-linux instead of depending on it
  - don't select util-linux-libs, there's no circular deps
  - squash both conditions together in .mk
  - fix check-package
