Use MODULE_NAME in stap-probe instead of IN_LIB
Define MODULE_NAME in the build command and define IN_MODULE using
MODULE_NAME. Verified that the generated code is unchanged on x86_64.
* Makeconfig (module-cppflags-real): Define MODULE_NAME
instead of IN_MODULE.
* include/libc-symbols.h (IN_MODULE): Define using
MODULE_NAME.
(PASTE_NAME, PASTE_NAME1): New macros.
* include/stap-probe.h (LIBC_PROBE_1): Use MODULE_NAME instead
of IN_LIB.
(STAP_PROBE_ASM): Likewise.
