ipmctl: fix build issue undefined reference to `main`HEADmaster

- `-pie` is only valid when linking executables (PIE), not shared
  libraries. So remove `-pie` from shared libraries linker flag.

+Subject: [PATCH] CMakeLists: fix build failure by removing -pie from shared
+ library targets
+
+With CMake 4.1.0 the build of libipmctl started failing with:
+
+  error: undefined reference to `main` in *.S
+
+- `-pie` is only valid when linking executables (PIE), not shared
+  libraries.
+- When applied to a shared library, the linker expects a `main`
+  symbol, causing the undefined reference error.
+- Remove `-pie` from shared libraries linker flag
+
+Upstream-Status: Submitted [https://github.com/intel/ipmctl/pull/221]
