ccache: Fix build on aarch64/clang

asm option checks in cmake gets it wrong to just check compiler options
to decide if SSE/AVX is supported, this accidentally then succeeds on
aarch64 and ends up compiler failures on aarch64 with clang

+Subject: [PATCH] blake3: Remove asm checks for sse/avx
+
+This ends up passing on clang/linux wrongly when building for aarch64
+the check in else part is good to detect the feature support and this
+check can be removed, it was setting
+
+HAVE_ASM_AVX* and HAVE_ASM_SSE* macros which are not used in the build
+anyway
+
+Upstream-Status: Submitted [https://github.com/ccache/ccache/pull/768]
