LexerParser: Do not override existing _POSIX_C_SOURCE definition
In commit f034b0f663 (CMake compilation: do not use compiler extensions,
2020-03-14, v3.18.0-rc1~494^2) we explicitly defined `_POSIX_C_SOURCE`
to ensure availability of POSIX APIs even when compiler extensions are
not enabled. Update the code to avoid redefining `_POSIX_C_SOURCE` if
it is already defined. This occurs when building our release binaries
as configured in `Utilities/Release/linux`, where we define
`_POSIX_C_SOURCE` explicitly on the compiler command line.
