The `-ffile-prefix-map` option also implies `-fprofile-prefix-map`,
which causes issues with Clang's source-based code coverage,
particularly in OSS-Fuzz builds
(see https://issues.oss-fuzz.com/issues/379122777).

This change partially reverts commit 788c132
from bitcoin#30811. For non-release
builds, only the `-fdebug-prefix-map` and `-fmacro-prefix-map` options
are applied.

01a7298 build: Avoid using the `-ffile-prefix-map` compiler option (Hennadii Stepanov)

Pull request description:

  This PR follows up on #30811, which inadvertently broke coverage builds:
  1. For GCC. See #31337 (comment).
  2. For [Clang's source-based code coverage](https://clang.llvm.org/docs/SourceBasedCodeCoverage.html) in the OSS-Fuzz environment due to its use of other options and a third party script. See https://issues.oss-fuzz.com/issues/379122777.

  The root cause of this regression is that the `-ffile-prefix-map` option implicitly applies:
  -  [`-fprofile-prefix-map`](https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html#index-fprofile-prefix-map) when using GCC.
  - [`-fcoverage-prefix-map`](https://clang.llvm.org/docs/ClangCommandLineReference.html#cmdoption-clang-fcoverage-prefix-map) when using Clang. ~This behaviour is not explicitly documented~ See llvm/llvm-project@994c544.

  With this PR, only the `-fdebug-prefix-map` and `-fmacro-prefix-map` options are applied.

  **Note for reviewers:** Please ensure that #30799 is not reintroduced.
