tsan: tsan_interface.h: make constants static

Note that in C++ the static keyword is implicit for const objects.
In C however it is not, and we get clashes at link time after
including the header from more than one C file:

lib.a(bar.o):(.rodata+0x0): multiple definition of `__tsan_mutex_linker_init'
lib.a(foo.o):(.rodata+0x0): first defined here
lib.a(bar.o):(.rodata+0xc): multiple definition of `__tsan_mutex_not_static'
lib.a(foo.o):(.rodata+0xc): first defined here
<snip>
Indeed both foo.o and bar.o define the clashing symbols:

$ nm foo.o
<snip>
0000000000000000 R __tsan_mutex_linker_init
000000000000000c R __tsan_mutex_not_static
<snip>
Fix it by explicitly making the constants static.
