sonic-plasma5-support-library: Build against sonic-sysguard-library instead of EPEL libksysguard

EPEL's libksysguard provides libprocesscore.so.10 but sonic-sysguard-library
provides libprocesscore.so.11. Replaced cmake(KSysGuard) BuildRequires with
sonic-sysguard-library-devel to link against the correct library version.
