Remove redundant sshd oval macro

[vojtapolasek]

Description:

• remove the oval_sshd_config macro
• replace its usage with sshd_oval_check macro

Rationale:

• there were two macros for checking of sshd config, this might cause confusion. Moreover, the removed macro was less powerful and effectively a subset of the sshd_oval_check macro.

Review Hints:

• run automatus on sshd_use_storng_ciphers rule
