gdb/linux-record: Fix sizes of sigaction and sigset_t
The values were mistakenly set to size of glibc's sigset_t (128 bytes)
and sigaction (140 or 152 bytes) instead of the kernel ones. The kernel
has 4 or 8 byte old_sigset_t, 8 byte sigset_t, 16 or 32 byte old_sigaction,
20 or 32 byte sigaction.
gdb/ChangeLog:
* aarch64-linux-tdep.c (aarch64_linux_init_abi): Fix size_sigaction,
size_sigset_t, size_old_sigaction, size_old_sigset_t.
* amd64-linux-tdep.c (amd64_linux_init_abi): Fix size_sigaction,
size_sigset_t, size_old_sigaction, size_old_sigset_t.
(amd64_x32_linux_init_abi): Fix size_sigaction, size_sigset_t,
size_old_sigaction, size_old_sigset_t.
* arm-linux-tdep.c (arm_linux_init_abi): Fix size_sigaction,
size_old_sigaction, size_old_sigset_t.
* i386-linux-tdep.c (i386_linux_init_abi): Fix size_sigaction,
size_old_sigaction, size_old_sigset_t.
* ppc-linux-tdep.c (ppc_init_linux_record_tdep): Fix size_sigaction,
size_sigset_t, size_old_sigaction, size_old_sigset_t.
