  [ASan][test] Skip Linux/odr_c_test.c on SPARC (#109111)

When ASan testing is enabled on SPARC as per PR #107405, the
```
  AddressSanitizer-sparc-linux :: TestCases/Linux/odr_c_test.c

```
test `FAIL`s on Linux/sparc64:
```
+ projects/compiler-rt/test/asan/SPARCLinuxConfig/TestCases/Linux/Output/odr_c_test.c.tmp
+ count 0
Expected 0 lines, got 13.

AddressSanitizer:DEADLYSIGNAL
=================================================================
==4165420==ERROR: AddressSanitizer: BUS on unknown address (pc 0x7012d5b4 bp 0xffa3b938 sp 0xffa3b8d0 T0)
==4165420==The signal is caused by a READ memory access.
==4165420==Hint: this fault was caused by a dereference of a high value address (see register values below).  Disassemble the provided pc to learn which register was used.
```
The test relies on an unaligned access, which cannot work on a
strict-alignment target like SPARC.

Thus this patch skips the test.

Tested on `sparc64-unknown-linux-gnu`.
