[compiler-rt] [profile] Enable testing Continuous mode on Linux (PR #121238)

[NAKAMURA Takumi via llvm-commits]

https://github.com/chapuni created https://github.com/llvm/llvm-project/pull/121238

Based on #115987, with the introduction of `REQUIRES: continuous-mode`.
Also Linux assumes `runtime_reloc`.

FIXME: image-with-no-counters.c is still excluded.
