    libc: Complete conversion to _getprogname from __progname
    
    The initial work to eliminate direct use of __progname was done years ago,
    but two items were missed: an extern keyword and libc_r conversion.  As a
    result, the symbol was classified as an object.  Before commit (R4.2):
    
    > readelf -a /lib/libc.so.8 | grep __progname
    00000032ac80  077600000006 R_X86_64_GLOB_DAT 00000000003506d0 __progname+0
      1910: 00000000003506d0     8 OBJECT  GLOBAL DEFAULT   24 __progname
       537: 00000000003506d0     8 OBJECT  GLOBAL DEFAULT   24 __progname
    
    After commit:
    
    >  readelf -a /lib/libc.so.8 | grep __progname
    0000003309c0  000400000006 R_X86_64_GLOB_DAT 0000000000000000 __progname+0
         4: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT  UND __progname
       545: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT  UND __progname
    
    The issue was reveal with libc symbol version testing, which also revealed
    the "environ" symbol has a similar issue.  The change matches how the
    FreeBSD analog works.
