SLE PCIDSS Fix problem with sshd_strong_kex default selector

[teacup-on-rockingchair]

Description:

• Replace usage of default variable selector for sshd_strong_kex variable in PCIDSS4 SLE profiles.

Rationale:

• Usage of default selector causes side effect oscap not being able to extract value, see Warning during build about invalid selectors in RHEL7?  #7222 , RHEL7 CIS Level 2 Server - not possible to connect to a machine after installation #7233

Current issue with the sshd_strong_kex variable on SLE15 build complains:

OpenSCAP Error: Invalid selector 'default' for xccdf:value/@id='xccdf_org.ssgproject.content_value_sshd_strong_kex'. Using null value instead. [/home/abuild/rpmbuild/BUILD/openscap-1.3.4/src/XCCDF_POLICY/xccdf_policy.c:2124]
