Use breakpad_getcontext on all Linux platforms missing getcontext
getcontext is also not available on musl libc, so generalize
breakpad_getcontext so it can be used as a fallback for non-Android
platforms as well.
On x86_64 and i386, ucontext_t uses an Android-specific offset for
storage of FP registers, since its sigset_t differs in size. So,
make the definition of MCONTEXT_FPREGS_MEM and UCONTEXT_FPREGS_MEM_OFFSET
conditional on whether we are building for Android.
On glibc and musl, signal.h and asm/sigcontext.h can't be included
together, so in breakpad_context_unittest.cc, only compare the libc
and kernel _fpstate when on Android.
