[compiler-rt] Increase kDlsymAllocPoolSize to fix test failures
Increase kDlsymAllocPoolSize on the release branch as discussed on bug
51620, as an alternative to backporting
cb0e14ce6dcdd614a7207f4ce6fcf81a164471ab and its dependencies.
The minimum size is 8192, as needed for the following test to pass:
AddressSanitizer-i386-linux :: TestCases/Linux/long-object-path.cpp
Fixes #51620
PR sanitizer/102911
* asan/asan_malloc_linux.cpp (kDlsymAllocPoolSize): Set it to
8192 on Linux.
