The zygote cannot have visiblity to LIBC_PLATFORM methods. Therefore, move __system_properties_reload to LIBC, and rename it __system_properties_zygote_reload, and indicate in comments that it should not be used by non-zygote apps Bug: 291814949 Test: atest CtsBionicRootTestCases Change-Id: Iee8fa0c76b740543c05a433393f2f4bef36d6d3d
