Subject: [PATCH] cmake: PETSc,SLEPc: match lowercase .pc pkg-config files

Upstream has moved to lowercase. PETSc has kept the mixed-case file for
compatibility, but SLEPc hasn't.

pkg_search_module takes multiple patterns and succeeds on first match,
so this commit is backward-compatible with older installations of PETSc,
SLEPc.
