libgomp: testsuite: Fix libgomp.c/alloc-pinned-3.c etc. for C23 on non-Linux

Since the switch to a C23 default, three libgomp tests FAIL on Solaris:

FAIL: libgomp.c/alloc-pinned-3.c (test for excess errors)
UNRESOLVED: libgomp.c/alloc-pinned-3.c compilation failed to produce executable
FAIL: libgomp.c/alloc-pinned-4.c (test for excess errors)
UNRESOLVED: libgomp.c/alloc-pinned-4.c compilation failed to produce executable
FAIL: libgomp.c/alloc-pinned-6.c (test for excess errors)
UNRESOLVED: libgomp.c/alloc-pinned-6.c compilation failed to produce executable

Excess errors:
/vol/gcc/src/hg/master/local/libgomp/testsuite/libgomp.c/alloc-pinned-3.c:104:3: error: too many arguments to function 'set_pin_limit'

Fixed by adding the missing size argument to the stub functions.

Tested on i386-pc-solaris2.11 and sparc-sun-solaris2.11.
