[PATCH] 21_strings/basic_string/capacity/wchar_t/18654.cc

http://www.cplusplus.com/reference/string/basic_string/reserve/

"Note that the resulting string capacity may be equal or greater than n."

The current testcase verifies that the capacity is exactly equal to
the length of the string or reserve value, but the standard allows the
capacity to be larger.  On AIX, the capacity is larger and the
testcase incorrectly fails.

Linux x86-64:
i: 4
str.length: 4
str.capacity: 4
str.capacity: 12
str.capacity: 8
str.capacity: 4

AIX:
i: 4
str.length: 4
str.capacity: 7   <-- i
str.capacity: 14  <-- i*3
str.capacity: 8   <-- i*2
str.capacity: 7   <-- default

* 21_strings/basic_string/capacity/wchar_t/18654.cc: Verify the
capacity is greater than or equal to the requested amount.
